Very cool game, deserves front-page. I like that there are both upgrades AND power-ups. I like the depth of the upgrades, and the quality of the game overall. I think what I like least is that maybe it takes too long to earn upgrades even with the loot upgrade.
Also, I appreciate the level of challenge vs. ease of play here...many shooters like this bombard you with retarded levels of bullets that make it impossible to win, but I noticed that while the first boss (for example) is fairly easy to beat, if you stand still too long you still can die really quickly.
Great balance, cool grafix, neat concept. 5/5
