Didn't like that the only way to change momentum was the grappling hook, didn't feel good to play. It didn't feel challenging, it just felt frustrating. The hitboxes on the character or spikes is off, was dying way too often to not actually touching the spikes.
It is a rather small game with there being an insane difficulty spike on the 3rd grapple. Pacing of the challenge could've been better or perhaps even better would to let the player get used to the grapple mechanics without any spikes first and THEN introduce the spikes.
