Damn Fine Game
Loved the number of upgrades, options, weapons, variety of enemies, tactics for the boss battles (though I didn't really use tactics on the last one. Just minigun and grenade launcher). I think the best part about it, though, is the cut scenes between fights. Excellent humor.
One possible glitch I noticed was when the screen was full of bunnies, I had the fully upgraded ally shooting, and I just acquired the minigun, shooting at the mechanical flying bunnies seemed buggy. Either it didn't detect me hitting them, it detected it but didn't show the ricochet animation, or the game was so crowded I wasn't hitting them, even though I thought I did.
One of the best games around.
