Overall, this game is ok.
The gameplay is ok. The visuals are ok. The sound design, the gimmick, it's just ok. You really didn't do anything that stands out to me. That's a huge problem, because no one will want to play a game that's just ok. You need to be great. You need to make a game that stands out. There is nothing in here that's really outstanding in my opinion.
It's not fun to die to invisible blocks over and over until you win. There's not a whole lot of skill involved here once you figure out where to go. And the reset to the beginning if you die too much is also annoying. You shouldn't punish people who are bad at your game, you should try to help them.
I don't really have much else to say. The movement speed is a bit fast. Sorry I didn't have a whole lot of positive stuff to say.
