Semicontrol is a simple puzzle game where you try to put the disc on the right in the red square by moving the disc on the left. Green squares reverses the movement relationship.
This game is a prototype. But the response I got for it was positive, so I decided to work on it more. There aren't much levels right now. No sound, no menu. But as it is, the game is playable alright.
Semicontrol is open source. If you want to see the source, download semicontrol.love, rename it to semicontrol.zip and unzip it. A LÖVE file is actually a renamed zip archive.
