For sure the best one I player out of those 40+ games I tried, very well done and the most impressive part is how the 10 second theme made it a lot better - you don't have to be awesome in dodging stuff all the time, you only need 10 seconds and this particular one is DONE. Some rooms were very difficult for me while others were a bit easy, but that's not something that is the game's fault most likely.
One way of fighting this one would be to give a "special" goal in each room, like a button you press before to make it harder, but get something in return (like a powerup that shortens the current room by 1s) - that can be used later.
Overall, this feels like a commercial release, awesome work!
