This game is amazing all around! The art, music, and gameplay work so well together, and I'm absolutely charmed. It definitely worked very well as a roguelike, and I love it.
One thing in particular I was in awe of was the art- the UI and game visuals were extremely cohesive, and the pops of color from the enemies really drew the eye. All the menus felt easy to navigate, and the map/bars/floor indicator were simple to read!
One thing I think the game could definitely benefit from is having a boss level, to add to the sense of progression and give the players something more to build up to. :)
