Got stuck as seen in the image on a level after button mashing asdw & asdf arrow keys together because I couldn't remember how to restart a level. Maybe keep those commands close by in game or in the comments below it. I also got stuck on the level because there is no way to jump up that I can see. I also don't understand the different tile types and why some you jump to, others you ignore and other you jump below. Very confusing. The jump/move mechanics were a bit of a turn off for me. As I got into more of the puzzles, I can see that it made sense but it still feels a bit low-class 2d to move in such a tiled fashion. I have no idea what all the gold blocks do and why there is is groups of them together.
