I am unsure of how to play this, cause there is no tutorial explaining anything, I tried the good old try all of the buttons that may right, manage to discover "E" is for opening the chest. Managed to move around and jump, somehow jumped right through the brown wall on the left never to be seen again. Tried one more time still clueless. Sorry for the 999 rooms I never got to see. The art style it's not bad, and it's consistent, which is good, it has the retro sort of feel, very nice, but please consider in the future that people have poor eyesight, so make the writing high contrast and chose fonts easy to read, it makes it more accessible.
