neon subsurface

This game was made in about 4 hours, so don't expect it to be to polished.
You cotroll the blue neon ship. But the engine is partially broken, so you can only fly up or down, but not straight forward. Your only hope is to toggle the direction in the right moment. But to keep the engine running, you need to stay beneath THE SURFACE. That's the red/green line in the middle. If you are above, you will loose fuel and below, you'll gain it.
Another danger are big blocks that are in your way and the speed-up panels. But luckily, there are also green panels that speed you down.

TL;DR:
Controls: SPACE = toggle direction
IMPORTANT: If the binaries don't work, that's because some libraries are missing, In that case, try the installer. Or, if you've got MonoGame instaled, compile it yourself.
In that case, if you've got some knowledge of Xamarin, you should be able to get it running on any OS. Windows Phone and Windows RT will be added in the next days, if you've got binaries for another platform, please drop a comment with a link.
