Hey there! Thanks for playing Necrosphere, I hope you are enjoying it. Today we've came up with some bugfixes and added a help menu with some requested features that can be accessed by pressing F1 ingame.
Help Menu (F1):
Mute Sound
Stop Audio Playback (gets rid of music)
Frameskip On/Off (select ON on slow computers)
Fullscreen/Windowed support
Purple Zone:
Changed a spike to fireball in a specific area to avoid getting Terry stuck
