Pretty simple concept, go as far as you can, gets harder as you go. Theres 2 things that make it slightly different than the previously stated game format, 1. being obviously the limited bullet count, forcing you to aim your jumps and time them, and 2. the rougelike aspect where every 100m or so you get an upgrade for your character, which gets reset once you die. Overall pretty neat game, I could suggest it for a roadtrip or something like that.
