Awesome creativity! It is a nice twist on time space games like Portal. It could do well from some more difficulty even though I did have a pretty hard time on some levels it seemed to taper off after a while. All in all, it's a great game with plenty of potential. Could even be an action platformer!
There are a few things wrong with this game. Someone got too happy with the whole physics thing. You hit an invisible bump and your trolley flips or bounces too high and hits the ceiling, or for some unknown reason or jolt your helmet comes off and hits you in the head. The bridges are finicky which does add challenge to the game but gets a little annoying. The trolley explodes if you land while braking and the guy still needs a seat belt or something!
The game's great but glitchy. Training at higher levels becomes way more difficult than necessary due to the glitches plus the shop doesn't have everything you unlock. I've been looking for the black color since I unlocked it and it cannot be found.
