Ambition of the Slimes(iOS/Google Play) (スライムの野望) is free to play, though it does offer some IAP in the form of items. Ads run in the upper corner of the screen, but there doesn't seem to be any way to pay to remove them.
The premise of the game is that you control a group of slimes that are rising up against the humans, who have conquered the world and brought it to the brink of ruin. Humans attack slimes without provocation. Now, it seems, is the time for payback.
Slimes are weak as poo. When they level up, they gain very modest increases to HP, attack, and defense, but at least insofar as I've played, those numbers are never significant. They can usually only withstand an attack or two before keeling over, and deal insignificant damage.
The slimes have discovered, however, that they can take over the bodies of humans. They do so by leaping down people's throats and commandeering the unfortunate meatbags.
There are many different kinds of slimes, each with a different ability. There are also 3 different elemental types, and every unit has one. Water beats Fire, Fire beats Grass, Grass beats Water.
Deciding which units to enslave, how to properly move and position your units, and what slimes/abilities to use seem to be the cruces of playing Ambition.
For those who would like to give it a whirl without knowing Japanese, on to the useful graphics!
1. Getting Started
Here we have a basic game menu. Functional.
2. Slime basics
Here are the basic stats for each slime. I think everything is pretty self explanatory except for "Fatigue." According to my research, this goes up as you use a slime. It will increase quicker as they reach higher levels. 0-99 fatigue have no effect, but once it reaches 100, the slime is too tired to attack. Fatigue seems to decrease over (real) time, by itself.
You can check out all your units from the game menu and rearrange them for your viewing pleasure.
3. World Map
Starting with a tutorial, you'll advance throughout several maps and take the fight to the humans. Each area brings up a screen like the one above. The important-to-note items here are the battle difficult at the top, expressed in stars; the enemy units; what slimes may join you if you win; the difficulty setting (normal or challenge); and the number of slimes you can deploy. One additional note about the difficulty setting - there are different levels of challenge that you can unlock as you beat the stage on easier settings. Harder battles offer better chances of awesome slime allies.
When you start a map, here are the (mostly) relevant items you'll see.
Excuse me for the crazy differences in image resolution. As I said, "quick and dirty."
Units that you take over will gain red eyes and a sick glow.
Just to give you an idea, yes, they literally do jump down people's throats. As pictured above.
Another fact to note - there are two advantages to be considered when picking your battles and positioning. Higher ground means less damage taken and more dished out. Type advantage translates similarly. And yes, you can have both a height and type advantage at the same time. Tons of damage.
A few other things I've learned so far:
- If a slime or its host dies in battle, it will "revive" when the fight is over. It won't gain as much exp, though.
- Slime abilities can be pretty useful. The worm-looking guy can cast "speed" - a buff that increases the target's max movement by one tile. The starting blue slime can cast "slow" and the little red dude has a better chance of commandeering difficult-to-enslave humans.
- Some humans are harder to take over than others. There are armor-clad knights which effectively can't be taken over unless you debuff them first with goo or break their armor. Bosses also appear to be especially difficult to capture.
- If you commandeer a human with the same element type as the slime you're using, the human you gain will receive a stat boost.
- You normally (see below for a qualification on this) don't keep any humans that you take over. I guess the slimes must make them jump off a cliff or something once the battle's finished...
- I forgot to note that the little yellow flags on some tiles indicate regeneration points. If you stick a unit on one of these spaces, at the beginning of their next turn they'll regain some HP (and certain spells/abilities will be recharged too, it appears). These are pretty important!
More Tips and Tricks:
1. Later on in the game you will get a slime "ヘルメス" (Hermes?!), whose special ability is to keep the human you took over for 1 battle. This means that if you take over an archer's body as ヘルメス (and stayed alive until you won the battle), you will have an archer replacing your ヘルメス within your units at your disposal. The archer's level does not show there because it will change depending on the difficulty of the next battle you bring your archer into (scales with enemys' level).
2. Fatigue does in fact decrease over time. However it is painfully slow, so I'd recommend grabbing a 2nd one if you find a slime that is useful (ワープスライム Warp Slime is a great example, sometimes you need two of them in the same battle anyways) so you can distribute the fatigue count. (Paul: This is a great tip about collecting more than one of a certain type. In fact I've been trying to grind out a second Warp Slime for a while now. =p)
3. During battle, on the bottom left side of the screen you can tap and go through different pages of information. One of the page shows the stats of the unit, and the probability of you enslaving that unit. They give you very useful information in terms of deciding who to take over, and also who to avoid. (If it says のっとり：０００％ then don't even bother trying) (Paul: An addendum to this is that the little red slime you start with has a somewhat improved chance of capturing some units. This is not reflected in the info displayed here - you have to actually select the のっとり option to see the % chance for them).

Update: Changed "Plant" to "Grass" (the kanji is 草, so "grass" is perhaps more literal).
Update: I shared the link to this mini guide with Altair Works, the game developers for Ambition, and they added it to their App Store and Google Play app descriptions! So "welcome" to anyone stopping by from those pages.
