Definitely not a fan of the control scheme. The puzzles themselves were fun to figure out, but personally I was hampered by not being able to move around, it distracted me from a lot of the puzzles. Conceptually, I think is game is awesome. The lazers and the cubes were a pretty engaging mechanic. I think with some good sound effects and some background music, (alongside completely reworking the controls) this game could be great. I think this sort of grid system lends itself better to controllers than keyboard. But hey, this is your first game, and that one note aside, it's a great start!
