This is a cool idea. I like the idea of the floor slowly falling down so you are forced to keep moving and be careful about your movement. I think it is a bit too hard to survive for 70 seconds though. Also, the falling objects fall outside of the platform area so they are impossible to reach.

It's an interesting idea for a game. Thanks for instructions becaouse I would not think about use of space without it. 

I like the use of a slowly changing platform that you must maneuver through bouncing around in this game! It is nice and simple and I think this game achieves what it is trying to do. The sound design is nice and adds to the game. When I started the game it was unclear to me which falling squares were dangerous or beneficial to me. This might be my lack of perception when it comes to colors and, this was very quickly solved but, this was a small issue I saw. I also was not able to find much relation between the gameplay and the theme of the game "the number 7." Despite this, still a nice little game about a bouncy block on a dangerous falling platform.

If possible, could you provide a macOS version of your game?
