Fun game with a good execution - the block physics are pretty cool!
The controls are very tricky to get used to, between the numbers, the keys for manipulating the character and the arrow keys for movement. A lot of the difficulty at the moment is coming from the complex controls as opposed to actual walls!
I had an issue with the player sprite disappearing from the bottom of the screen - not sure if that is intentional or if it was being masked by something else...
All in all a good concept inspired by a real world game show - just needs a little bit of fine tuning. Congratulations on your submission!
