FFFFFUUUUUUUUU
It's been at least twice i accidentally quit my game just because i kept the mouse button pressed while opening the power-up menu, then releasing the lb on the "quit" button... i was at level 26!!!! Aside this minor, but really frustrating stain, there are two things i hate: those grunts when they come in swarms of all dimension from every direction, while the others won't let you escape safely, it makes quite impossible for me to get even a 500 hit chain, then you add a little freakin' splitter disguised as a pixel and you vanquished at least fifteen minutes of efforts... But now i cooled down, and i say that's amazing! I liked this even better than Cell warfare, especially for the permanent upgrades and bonus points for achievements, controls respond perfectly, and the graphics is cool while leaving the gameplay lag-free even on my crappy pc... Truly a great job!
