Every time you stand (i.e. feet touch the ground or a block) you restore your ability to spin. You can use your spin while you're standing or after you've dropped off a ledge, but once you've used it you need to land again before you can spin again. Is this consistent with your understanding of the controls?
Planning when and how to use your spin is the heart of the game, so I'm reluctant to change it. That probably sounds like I'm unwilling to take on feedback, but that's not my intention.
Is the problem that the spin behaviour is inconsistent or that it isn't well explained? I had similar feedback during development of episode 1, then inserted prompts into the first few rooms to explain the controls as you go.
Have you played episode 1? Admittedly in episode 2 the controls aren't re-explained, but rather rely on the player having played episode 1.
Thanks for taking the time to play my game. I appreciate it! I'll keep thinking about ways to make the spin mechanic less confusing, and of course I'm glad to hear any other ideas you have in this area.
