It's a good puzzle game, that last one really had me thinking. However, I do feel like there's no real snap to this grid-based movement. This made some elements (including that last puzzle) hard to impossible. I think if the character snapped into place in a more grid-based movement (instead of this weird hybrid fealing that you had going here) you can make as many puzzles as you want. Other than that, I do think that the welding torch should come with some kind of detach option, but that's just me. Other than that, it was just fine.
