First update after seeing some feedback from reviewers & streamers:

• More optimizations of texture & object (pre)loading - massively reducing in-game jitter (FPS Spikes)
• Video options now available within the Options area
• Game targetted FPS can now be set within options (if you want to reduce CPU usage, or if you'd prefer more stable FPS for stream recording)
• New power-up "Magic Mushroom"
