I liked the idea and it was nice to have the visual clues unlike some similar games I've played where you just have to guess and try and remember if you've fed them and how long ago etc. I think, with a little more polish, this could be a great game! At the moment, it feels a little awkward to play, possibly because the hitboxes on the icons are too small so I don't always manage to pick up the items I've bought straight away. Great idea though and a good job for the amount of time you had!

Very good idea, the purchase system works very well.

I don't really understand why my slims dies, so add GUI or fx on slimes to indicate what slimes need (food...). Also that's not really clear what is the difference in a slime behaviour.
Keep improve the game, polish it and it will be great.

Nice job.
