I was certain that the creatures are "enemies" that would harm me. Especially the ones with the spikes. I had no idea they actually recover the energy. Anyway, thanks for telling me that and for your time.
Okay, now that I learned that, I was able to reach level 7. I got nearly insta-killed after reaching it. The way the speed increases definitely needs some adjustements. Maybe make it so that after level 6 or so the speed no longer increases and it just becomes free mode?
