It's incredible. I only hope for multiplayer one day.
Only thing I've noticed, either pierce cannons/beams cause lag, or the combination of both. Boosting firefox priority seems to help, so nots sure what can be done about that.
The apocalypse cannon DID cause an apocalypse ROFL! My game was frozen, couldn't shoot or move, maybe because I stayed in the bubble too long. I went to another bubble but I was froze, enemies couldn't shoot, I couldn't shoot, static, stuck in position, but enemies could move.
All the cannons seem to have the same near uselessness except for the begginer cannons... Which are cheaper and always better. Better refire... equal range to everything... WTH were they thinking?
