The game's arts are really well done. The platform (grass, stones etc.) looks a little plain compared to the characters and animations (I think they are not a part of the asset pack you used). The game has some bugs. except for these 2 things, I would say the game is well made. the controls are responsive and satisfying to use, the animation doesn't feel slow, and the game is fairly hard.
Good luck on the Game Jam!
If you can, then rate our game 'Thoughtful Horrors' (We made the game in 2 days since we didn't have much time.)
