the randomness part of the game is very negligible, I wasn't even aware of it until reading the description. also there is no challenge whatsoever until the pointer goes away, at which point it becomes too difficult. 

I couldn't get the "dice" part of it but it was cool for a simple project!

Very neat and simple concept indeed. I had fun!

it could be a good "one-button" mobile game.

It lacks maybe some modifier but overall a little enjoyable game. Good job!

Clean graphics and a easy to understand mechanic make for an overall enjoyable game, I liked it :)

Lovely game

The idea is good but I felt like the execution lacked a little, few suggestions
- Ability to cancel the action (AFAIK you can't cancel once spacebar is pressed)
- As others have pointed be able to see modifier and what the dice has rolled internally
- Another modifier that blinks the bar
- Two dimensional motion i.e. Bar goes moves freely maybe in zig-zag motion

Reminds me of these old mobile games in the Doodle Jump era. 

The dice theme does not push through to the player. If there are modifiers, have them pop up so I know what to do. 

For me, at some point, the platforms just become very small and then I die. The game isn't very forgiving of near misses. The last time I died a bug took away the blue landing zone bar.

I noticed the Tron inspiration.

One idea for improvement would be to place the landing zone bar a bit in front of the current landing spot so I don't have to wait as long for the thing to go where I want it, and also let us move the bar ahead while the ball is in the air.

Nice, mindless game, would play waiting for the bus.

I quite liked the games mechanic and found it quite relaxing. My only minor nitpick would be that you die sometimes even if you are mostly on the platform.

Other than that good job!
