I won ! (1 : 35)
The game is great. The damage system is an excellent implementation of theme, it's super fun turning around you to move backward because you can't go forward or doing a 315° to turn the other way, generally dying during the process. The tank speed and projectile speed are perfect, the game is hard but fair just as I like it. The length of the battefield was the right one too, it was satisfying to finally manage to reach the end, although even just a bit smaller might have been fine too.
I had a lot of fun playing the game, well done !
