The enter key only seems to work when the game is in fullscreen (Chrome W10).
Pretty fun and funny game and I love the little details, the completely dark level is bullshit though and I almost gave up there but I'm so glad I didn't, it actually gets very... interesting later on and I recommend people to play it until the end.
I honestly could see this being developed into a full game with some more involved gameplay, most of the gimmicks are pointless since the most effective strategy doesn't change.
I'm apparently SUPER DUPER EVIL AND IRREDEEMABLE AND EVIL too.
