Well the firerate is supposed to be that low. If you upgrade enough you are gonna be able to fire a bullet per 0.5 seconds. You just gotta keep upgrading and grinding. Btw if you press F you will teleport back to spawn
Oo, F to teleport back would have saved a ton of time ha, I got far enough to do a couple upgrades so it was more a matter of persevering through. Can only do so much grinding though with 105 games to rate lol
