Yeah, the polish its mostly because I took hard advantage of the pitch black ocean. Most of the game its like three assets and the endless dark, the wall its a 64x64 tile repeated forever for example, it would really hard to pull this off in another environment where you can't hide most of everything!
And you're right, it say press instead of hold, I had another person have the same problem in fact, it's a really quick fix so I'll do it right after ratings are finished!
