Bugs fixed and new features!

This Update includes quite a few bug fixes and contributes to a better experience while playing.

The Spawner-Algorithm has been improved to allow more accurate spawn rates and allow for much higher spawn rates of up to about 3000 Balls per second. 

We also improved performance a bit and lowered the graphics settings to allow for fluid gameplay even on low-end devices. (A menu for these settings is still in progress and should be available soon)

Many new upgrades and upgrade levels have been added and a Prestige is also possible!
