Awesome challenge!

Puzzles are tough but possible and often imaginative, which I really like. The instructions can be a bit confusing, especially if you don't know much geometry, but other than that, the concept is really cool.
I'd like to see some puzzles where we are allowed to use certain angle tools (like constructing a 45 degree angle anywhere)

Love this dev

Every app I've tried from these guys is phenomenal. Great, innovative learning apps. I can't put them down. So much potential here - can't wait to see what's next.

Lots of fun and challenging.

I'm hoping that new levels will be added, but the number of levels included is well worth the price.

I'd be willing to pay for more!
