Interesting gameplay mechanics pared up with some rather pleasant minimalist graphics. The level design was overall quite good and often proved to be a genuine challenge. However one issue I had with the game was that sometimes the beam just seemed to look onto the ball, despite me aiming a fair bit away from the ball. I don't know if it was done intentionally to increase the challenge of getting through certain gaps but it could prove to be annoying when you were aiming at the wall next to the ball, and your grapple beam would still go right of your mouse to lock onto the ball instead.
Overall it did fit the theme of the gamejam very well and I found it to be a very competent, interesting and most of all, fun entry into this years game jam. Well done!
