A little buggy but making an auto-battler in a week is no small feat, so you did an impressive job. I like the cute animal graphics and the game itself is pretty addicting. My favorite part of the game though would probably be the variety of animal characters and their names.
It does take some time to fully understand the mechanics, but I think that's just in the nature of auto-battlers. Most of my qualms with this game are just bugs and should be easily fixed. The bug where you can't move a unit back to the bench really makes this game a lot more difficult than it should be, unfortunately.
Overall, very impressive work and I love the animal characters. Great job!
