I love the concept of a welding game. I just don't find this well executed.
I am not going to get super nit-picky because the concept is good and I did enjoy it but the frustration level made it not as fun as I thought it would be. I weld in real life so some things about this bug me. Mainly the fact that the welds restart if you move the slightest bit wrong. Once you lay down weld you should be able to pick up where you broke the arc. Also sometimes the "hit area" for the lines is way too small. Also it is very annoying to have the clock going while I am reading or clicking out of the instructions.
I think that if this game were made without this tediousness, and was maybe added some extra touches it would feel more like a welding game than a mouse avoidal game. (like perhaps an acetylene cutting torch with a flame, a motion for striking the arc ect) Overall I liked it though.
