Cube Runner V2

I have just updated my game I added a lot of features to Infinite Mode I fixed a problem with the blocks being to close I also made it so you go faster during time. I made a coin system. When you get 3 coins you jump very far. I also added blue powerups which make you jump over one block.

Blocks can appear too close to one another in infinite mode to anticipate and navigate properly. A block spawned in the middle, so I went to the left, but, right as I began to pass the block, another block spawned almost immediately behind it. I had no time to move to avoid it, but, it wouldn't have matter if I had time, the block covered the entire left side, so I would have had to swing a sharp right to narrowly avoid it, and likely would have flown off the edge.

My suggestion:
Create a minimum distance between blocks that increases with the speed of the cube.
Create "handicaps" for players such as: Walls to prevent them from falling; multiple lives so they don't lose as soon as they collide with a block.
High scores? Longest distance traveled, number of attempts over 10,000 score?
Powerups that can let the player jump over a block once, push a block out of the way, give the player an additional life, make the player invulnerable for 5 seconds?

Please add notes and tell me what I could change.
