I really wanted to play this game more because the concept was really fun, but the very fast timer that forced me to move or restart was pretty frustrating on top of the various different rules in each room. 

Looking cool, love the style... it kinda reminds me of the old school Mario games!!

Hello, really cool game, especially the movement, it fells pretty good, and the random challenge is a great concept and sometimes nice, but other times i felt that it's way too hard, but overall, i believe it could be an interesting and really fun game if it was balanced and fiished after the jam. Some music and sounds would be also cool, but it is understandable not having them since the jam was so short.

I really liked this game, I thought the jumping was great and the animations were really smooth. However some of the challenges were frustrating to the point of not being fun - specifically there was one that flipped the entire screen every few seconds/key press and I had to keep going back challenges to progress. The concept is great though!

Nice game. I like  the concept of invisibility.

Everything was a bit small, I suggest rendering your game at a lower resolution and scaling it up. For example rendering it at 320x240 and then scaling it up to 1280x720. That way each real pixel is 4 screenpixel. Kind of like in your screenshot.

The jump is a bit too floaty for my liking but its fine.
