Collider®

This is an app originally made by another developer and bought by this one. It is pretty much the same as the original with a few major differences. First it is MUCH shorter. I think the original had somewhere between 65 and 80 levels. I assume this developer will introduce the levels as updates but for the money they really should give you all of them at once. The original also had no ads at all. I'm one of those people who really think that any app you pay for should have no ads at all. This review would be 3 or 4 stars if it wasn't for the ads. Beyond that the play and layouts are identical to the original except the backgrounds are cheaper looking and not as detailed. The original was .99 so if this version goes any higher than that it's not worth it, at least until they introduce all of the original levels. Worth a dollar if they keep updating levels. I still like the original more, though.

Once you get the hang of Collider, it's an addictive challenge that keeps your brain gears turning until all levels have been solved... unlike most other similar puzzlers that you just have to put down after awhile, incomplete and frustrating. Collider's simple but mesmerizing music track is perfect for keeping the right amount of audible tension to assist your concentration as you hone in on the perfect placement & timing to solve each level. My only request would be just a little more crispness, brightness and variety in the color schemes as you move along. Other than that, I'll be anxiously awaiting an update that brings more levels to keep my brain sharp! Thanks, Developers, for a really fun block of time!

I have to say, this was enjoyable. The experiments were challenging, the idea was innovative, and the look was appealing. HOWEVER, the amount of levels was pitiful, the idea of some the levels was simply guessing/lucky timing, and the amount of time I spent playing was literally ten minutes. If the creators of the app keep to their promise and make more levels, I see this app as being a very good one. Until then, it's above average, but not mind-blowing.

This app was definitely worth the .99 I paid for it - it takes a pretty tricky mind to come up with the puzzles in the first place, even though it only took me a little while to solve them all. For folks who aren't into physics (like me) it was very entertaining. Waiting for the next set of puzzles!

My 7 year old loves this game. I like him playing these rather meaningless games. This game allows him to challenge his mind and try to solve problems in a way that he will be able to apply later in life. Thank you for creating a game that is great for entertainment and education.
