First of all, I love the style of the game and the whole arcady atmosphere, but there are two or three things you could improve. The first one is the controls i pressed every key on the keyboard until i found that "Z" was the key to progress in the menu, then the tutorial said the rest. Maybe just be more clear on keyboard shortcuts. The second thing is the colors, they are amazing and fit very well in the game! But i could find one light brown, one purple-ish brown that is darker, one clear blue and one light yellow. That adds up to four colours which fits the requirements, but then some texts are also in white which adds a fifth colour? Or is white not a colour and it is therefore ok? I dunno. Also at one point of the game i started spamming with the flashlight and certainly no enemies spawned anymore? Maybe a glitch of some kind? And lastly you should just use an int somewhere because 6036.000000004 is hell of an ugly number. Great game overall! What i pointed out was just minor stuff that i saw in case you wanted to improve the game. My experience was amazing nonetheless!
