My review....
Quick breakdown.
Controls: Started out very smooth, but after a while the game began to lag no other game I have played has caused my computer to lag. At times I would click and nothing would happen other times I would click and a few seconds later it would fire. (notes I can run skyrim at highest settings without lag). Still going to give it an 8 out of 10.
Sound: At first the sound was good, but the same clip was playing constantly for each level and began to grate on me. But it does fit with the game and the type of game it is. 6 out of 10.
Graphics: Very simple, and straight forward graphics, Looks smooth and well designed, 9/10
Level Design: The first few levels, no problem, as it should be so people understands how the game works. But it should get harder. 4 out of ten.
Game over all. Concept is good, and could easily be expanded on, a few simple tweeks and this game could really be a 5/5 10/10. Changes I would make, is the level system needs to go, puzzle 1, 2, 3, 4, 5, 6, exec... I did puzzle 20 before 6... I know it's not that big of a deal, but if you want someone to progress down a path, then when i'm on segment 20 Thats when I should get Puzzle 20. If you are wanting to have it branch kind of like it does now, thats fine, just a small aspect that hit an ocd. With the level design I give the game overall a 6.75, The game lost it's fun factor and that killed a good % for me. Mostly because of the controls.
