The representation of the theme is quite interesting and has a lot of potentials. I liked that sometimes the player has to choose between picking a power-up or a speed buster depending on the situation of each vehicle. I've thought that both vehicles were linked (maybe past and future, or two parallel dimensions), which could be an intriguing story.
The visual style and sound effects could be better, at the moment are kind of funny, especially the speed buster.
On my first two tries I didn't understand how the acceleration worked, maybe it should be explicit in the game's description.
If you could comment and rate our game, we would appreciate it.
