Those red blocks are something else and the game can be pretty hard but have to say it is a fun game that keeps you wanting more

~X~

There isn't really anything you can do to get more blue dots, so you might as well have just made the score increase based on how much time you're alive.

I don't get any points when I collect the blue dots. That's...not good. I think.

Overall, I think this could make for a great mobile game that would sell reasonably well.

Its main flaw is that it has unfair difficulty. By unfair I mean were the player doesn't feel its his/her fault. People complain about the red squares because the yellow one is too hard to control so not dying starts involving luck mostly and the player feels he/she lacks agency.
I think the yellow square should instantly move at a predefined speed instead of gradually accelerating. This allows you to change direction quickly and predictably and I think will work better for this kind of game.

Another thing I noticed is that I end up not moving the platform at all. Maybe focusing on the platform, the yellow square and the red squares is too much, but with better controls I think it'll be possible to stay alive without having to move the platform, and moving the platform can become an emergency-only pro technique.

Also another thing that feels unfair is letting the character go off-screen. You can be hit by red squares and you can't see them. I think the main character should not be able to go-off screen.

Other than that, I think the basic gameplay elements are really fun.

Difficult to reach the portal as the red squares always kill you less than half-way in the air..all I can do is just stay on here long enough to collect the 10-minute medal then quit and go on to a different game..Get rid of the red squares and you'd have a challenging game..
