I really dislike how the art varies from pixel art to quite blurry graphics or just straight up hd graphics, the overall game loop is really nice but i find that the audio all around is a bit unfitting. its definitely not a bad game though, i just think it lacks a lot of polish.
i'd say try to have a strict range of how bit your pixel art can be, the worst thing you can do is put a lot of effort into art that doesn't even fit into the game(from which i've got no idea if this is an art pack or something other). and for the audio, i don't know what the creative process for the game was, but i'd say try to make everything audio related after you have a general feel for how the game will play out, that way it will be more fitting. there are lots of easy to use sfx generators like chiptune, but sometimes it might be easier to get what you want by recording it on a mic. but still a pretty fun game, cant wait to see what yall come up with in the future:3
