It's really cool! It's very Pokémon-like, and the art is very cool. The art and battle system are awesome. The songs are actually pretty good! And I had a lot of fun! There could be attack animations or even just making a monster move across the screen, there's no signs for attacks, or even explanation to what they do, I just assume the first attack is strong but centered, and the second is weak but widespread.
However, I gotta say one thing, sometimes, the song ends, and it plays an eerie static, is that supposed to be in the game? Also, the jump feels a bit clunky. And the bunny humanoid's character design....... Better not even say anything.
Overall, excellent work! It's a very polished game!
