Onslaught is fun, except that the one and only strategy is to build 3 missle silos at the best points, fully upgrade their damage, get their range and rate upgraded past the 110 and 160 cost upgrades so they have 5 misssles surrounding them at all times, and after you max all their damage you build a cannon, max its range and attack, and use it for the combo ONLY. If it were more balanced it would be much more enjoyable.
I give it a 5 out of 5, the sound is awesome and I like hard games.
You should put a life modifier(easy mode, you have 10 lives no badesearned) on if you want people to hear the whole song(Or give us a link to the music).
I always disliked pang games, but I could respect them and their high difficulty. But this one the graphics are just printed backgrounds and bad simple avatars, the dart is slow and makes no sense(normally in pang games don't they fire a gun that doesn't stay on the ground?) and the sound s pretty bad. I only give it a 2, but a 1.5/5 is more accurate.
