Red Faction!
I liked this game, mainly for shooting at the walls. It reminded me of Red Faction where you could dig tunnels using rocket and grenades. i would set ammo infinite and just have fun. Its rare to see a game that incorporates something like that. i just wish there was a fun mode with unlimited shots.
Gameplay itself was fun, i wish i didn't get hurt so much by walls, unless i realize i hit right away i might instantly die lol. the fast power up is kinda annoying, going fast made it MUCH easier to hit walls, but i just chose not to pick it up anymore so problem solved.
Good job!
