are there supposed to be big black rectangles blocking out most of the level?
i suppose not and its just a bug, but if it is then its a very questionable mechanic ngl
edit: the game is beatable even with the bug, but even then the fact that my first blind playthrough of the game was LITERALLY a (mostly) blind playthrough is not very good.
the game is far too empty in my opinion, the enemies dont kill you and the collectables dont do anything. while the visual style is very charming and the music is good, the level design and the programming is erm.. lame!!
