I think what's most impressive is the fact the game manages to still keep me not only playing, but engaged even when I don't know where I'm supposed to be going or where I'm going, the game locks me in a trance, auto-pilot-like state where I just am going through it.
This is a very good game, one which I sincerely want to get made.
6/5, the only thing I can critique are the dashing controls...and the fish enemies.
Best of luck, matey, and cheers!
