Feedback from the judges

Pedro Fortuna: Good game concept. Pretty hard to master, if you ask me. You could implement different levels of difficulty, that would map to different game speeds. Slower game is easier. Right now the default is kinda hard for the more advanced levels. Original concept, aligned with the contest theme. Good job!

Abiyasa Suhardi: Very addictive & torturing game at the same time ;-)

Mike Cook: Wow! This was a hard game. I'm always drawn in to platformers in jams though, I love a good puzzle mechanic. This was fun! 133 deaths in all, had a few moments where I was definitely on the verge of quitting though! Haha. I'd love to see this expanded a bit - maybe a more forgiving control system for some of the jumping-then-switching levels, and possibly some extra mechanics - other objects that react to the switch, or a timer that auto-switches every few seconds!

Christer Kaitila: so fun and fast and HARD in a good way! great work.

Jimmy Joe McGurl: What an amazing game!! Addictive fun, with simple elegance and a fantastic difficulty curve. The addition of a level editor gives me butterflies. I'm in love
