I enjoyed the game quite a bit and the presentation was great. I didn't make it to the level in the cover art unfortunately, so I'm not sure if I experienced every mechanic. Make sure if you have a difficult game to frontload what you consider to be the most interesting features and mechanics knowing that not everyone will make it through it. The most important rule about a game with punishing difficulty/precision platforming is that you have to make sure that it's really easy to get back into the game after a death. It was the right call to not give the player any air control... but the level where I got frustrated had me waiting 7 seconds between retries.

I got stuck at the one that requires you to time the fall so that the rotate left changes your fall direction and avoids the spikes. I tried it a bunch, but because of the long initial timer to start moving I ended up bailing. To be fair, my platforming skills do not exceed World 2 of Super Meat Boy. But I honestly would have kept going if there was something to do in that first seven seconds, so I think it's just a specific level design problem and not really a game design issue. Is there later a mechanic to speed up/slow down the clock?
