Fun game! Really interesting interpretation of the theme, I enjoyed the game and the art style is great. Only things I'd say are maybe to reduce the map size or change the starting speed, it can feel quite sluggish early on, or perhaps have the player get a level up instantly so they know movement speed upgrades are a thing fast, I accidentally chose an upgrade sometimes because I was attacking so a delay before picking would be good, it would also be nice to have an indicator of where the enemies are, sometimes I was roaming around for a long time without doing anything. Overall a really great experience just wanted to highlight those bits.
