The first in my series of puzzles inspired by real physics.

Which falls fastest: a weighted cube, a reflection cube, a turret, or you? If it wasn't for air resistance, they would fall at exactly the same rate! (9.80 m/s/s or 32 ft/s/s). Still, even with air resistance, the time it takes each of these objects to hit the ground is very close.

Oct. 8 update: Overhauled first stage to make cube retrieval easier. Also added respawn button for cubes. Tweeked faithplate trajectories and ceiling. A lot of trial-and-error accomplished.

A bit of a chore...tiresome -- yet great thinking at the end....overall nice.

OK, so a turret apparently falls slightly faster than anything else and yet it can't weigh down buttons unlike in the original game....strange indeed.

Took me a little while, but eventually figured it out. Thank you. :)

Pretty test. I did not find it difficult, but it was fun.

Very original, very clever, it's fun to play, but not perfect. The trick with reflection cube could fail if not perfectly positioned, and the last jump require a bit of timing. As for difficulty this could be between easy and medium. 7.5/10

Turrets highly explosive. Handle with care

Some of those things I hadn't seen before.
