Cool game!
It was really awesome! I didn't get any close to dying but thats probably cuz i played on normal difficulty... anyway yeah save option would be fantastic and also it would be cool if you could restart the levels but with the perks you already have just to get all the perks for fun cuz i really wanted to unlock them all but i finished the game before doing so T_T and also i never got to try the last gun (laser blazer) and the Titanium armor... still good game
