Currently playing on chrome and its working fine. Only annoyance is, the times X bonus covers the space tourism upgrade button, when doing multiple upgrades in a row.
Anyone having trouble with the level 20 insane boss. I used 6 Final tech armors, 2 Night Helmets, 3 final tech protector droids, 2 health potion pro, and the mustard pro medic suit.
Don't worry about your dps. Just concentrate on firing the full power cannon on the open eye. Use dropped shield when the tenatacles start moving apart. Don't move too far forward or you'll fall off the boat.
