Pretty cool visual style to the game! It's pretty impressive that you managed to implement 3 different classes. I feel like the warrior suffers by being melee though, considering how hard the enemies hit. I think you have a pretty strong core to a game here, and the concept is pretty original! If you continue to work on it some things I feel would benefit would be: more refined/polished movement, some sort of grace period/area when starting a new level so you're not immediately overwhelmed, and either health bars for enemies or a visual damage state. Some extra time to read the text between levels would be great too 😅 All in all great entry and really unique and cool style!
