loved it, a second?
this was a great gaem, but it got easy very quickly after i got overkill, i got the laser cannon and all of a sudden i have so much experience i am unbeatable, so maybe it was kind of a mistake to make a repair full health, i can sit and wait then blast them all gain 10000+ exp and heal both me and base for 3000 or whatever, then upgrade a couple times and the more i go the more enemies that come at me and the more xp for overkill and bloodlust i get, though blodlust was nice, and perhaps a system where you upgrade slowly, maybe 10 20 then 30% bullet upgrade just a thought, i love this game though.
