Your game is awesome. The secrets are well-hidden and rewarding. The difficulty curve is pitch-perfect, with unlockable challenges that are actually worth playing. The retro feel is spot-on. ***The controls are customizeable.*** You clearly understand what makes action/adventure games fun.
You should collaborate with xdanond again. Story like Starwish + gameplay like Snailiad = a game I would pay money for.
Or, you know, just make a Snailiad sequel. Whatever.
