Remember Bridge Builder. What about Incredible Machine? I you liked those, you'll definitely love Armadillo Run.
Put your brains to some use in order to get you're armadillo to finish 50+ addicting levels of basic physics.
You can download a demo version and if it tickles your fancy you can get a full version for measly €15.
I just lost a day to this incredibly addictive time waster. I gave up on level 37 but haven't stopped thiniking about the situation. I hope I can get some sleep tonight.
PS: I think this is first YouTube video I linked EVER. That's what I call "late to a party"!
