After watching some people playing the game after submission it indeed seems incredibly hard to learn. Curse of the game dev's knowledge about their own game I guess! As for the mechanics, the arrow keys point your character in the direction you input (with a controller, it's with the analog stick) in the game world. Spacebar increases momentum quite a lot if timed correctly while exiting the droplets. The X button is probably the most confusing, but it essentially converts any speed into lateral movement, and (unfortunately!) is almost essential to progress. It's really a shame we didn't have time to play-test or include some tutorials in-game.
It's really unfortunate you didn't get to experience more than the first layer. We have included a little playthrough video on the game's page if you want to at least partially experience the rest of it. There are also some hints on the page if you care to try playing it again.
Thanks a lot for the very positive review and for playing our game! We really appreciate it.
