itd be good to add some instructions, especially at the opening screen we have no indication of what button starts the game or if its functioning properly. ofc spacebar isnt hard to find but it still was not very clear and i wasnt sure if the game was just glitching or still loading at first. also it seems like the character in the center of the first room is your avatar, so i kept trying to walk downwards and it just goes "i give up"... its really not user friendly in many ways. it would also be much better if we didnt have to tap the keys for every space we move. that makes sense if the game is a rougelike dungeon crawler but the enemies arent taking turns so im not sure why its set up this way.
combat is basically just token collection, i have no indication that theres any danger whatsoever or if i or the enemies have an hp meter. is there any motivation to even fight the enemies? if im not gaining xp and i have no real objective besides "get to the end" then im not sure why the slimes are even there
was there any point to the burger whatsoever?
this is a good start i guess but its hardly much more than a 1 minute pixelated walking simulator and has very little content to draw my interest

Very cool game but if you could add sounds and if you could make more levels it would be great and i would give you more stars...
