Solid metroid worship, but it truly was worship. Even dismissing that, this game is so close to being actually really fun if it weren't for missing polish and reducing annoyances. Things like coyote time on jumping, or having blocks disappear slower. However! Thanks to all the work you put in, these are (hopefully) easily changeable things. Tweak it until it feels right and then pass it to a friend, and tweak it until it feels right to you both.
