Great puzzle game...not paying $8 for full version – Crafty Cut - Touch Press Games Review

This is a beautiful, brain challenging & well made game. Two issues: 1) I found it irritating when I failed the levels that had the "3D" layout and the time/energy bar count down. Each time you move a piece your "energy" is going down (and you fail the level if it gets to the end). Typically, this would be fine, but because the pieces are all over this 3D 'board', you almost always have to move each piece several time to get them in the same space. 2) There are a good number of levels available in the free version. However, at some point, there is a pop-up, ad-like box talking about subscribing to all the games the developers make (for somewhere around $45). Or, in a small little box in the bottom-right of this big ad box, you can buy the rest of this game for $7.99. I'm not paying that because 1) I think it's too high, and 2) I don't know what I'll be getting for the $8...
