It seems like it could have an interesting idea. Visually, it reminds me of old flash puzzle/timing games. I would like to see where this goes. Keep working on it.
Some issues:
- ending the game when going off screen is not a fun experience
- the position the player has to be in for certain blocks to move or not move is unclear. It would be better if one knew where they had to go to get out of danger.
- The effect of E was not really clear. The times when the player can press E are not really clear. The purpose of using E to stop the blocks in the 3rd level is not clear.
