The idea was great! And although the controls were somewhat hard to master, the gameplay was very nice. The problem for me was that aiming was a hastle, especially with the possibly inverted mouse, although the laser helped. It was also annoying to replay the level everytime you died, as one guy said below, checkpoints would be nice.
Overall, great game! And I would hope it would get polished and published into a full on title.
And now for the shameless ad, sorry, please come and play (and give the wall a new coat of paint), need the ratings: https://darylsteak.itch.io/paint-the-walls-red-gmtk-jam
