Really addicting because of the simple mechanics, a shallow learning curve, and challenging design. It got really fun once the different types of magnets were mixed together.
My one complaint is that it is hard to tell on some of the stages, especially the later ones, where the exit is.
Amazing game. The only complaint I have is sometimes the zipline sound glitches and stays on continuously, and that's really annoying. Might just be me.
The zipline sound problems should be fixed in the latest update, it should say "Version 1.03" on the title screen now.
