Thanks for playing it again. I can imagine not streaming makes it easier to concentrate.
The colours for unlocks make sense to me, and were suggested by colourblind anons, but yes icons showing ulocked state is something I want to do in future.
Action card speed should be adjusted in upcoming update.
Action freeze button not changing the icon, but freezing itself is a great idea.
After a sprint jump, I find the air slowing a bit harsh. It's nice to to do precise jumps, but it kinda ruin the momentum for me
Were you attempting bunny hopping, or something? Yes, the jump acting that way is for precise platforming and not moving around with jumps. If you want to travel fast, then try jumping and then dashing in air. There are also more unlockable abilities that make it even more extreme. Comboing air jumps with multiple dashes makes you fly really far too.
Have you thought of having the power jump starting its charge when you crouch instead of holding space? Or being able to charge it while still being able to move? I would find it more fluid for a speedrun
Power Jump just like other jumps changes its power depending on if you are crouching or not. As for it stopping your movement, it was fully intentional to make it that way. It's supposed to be a slow, but powerful way of getting a lot of height that requires extra planning, so making it fluid was not my intention (it's still good for speedrunning since it allows you to skip many platforming challenges in vertical rooms). Hover Jump is faster, and more precise, but costs more mana, and Multi Jump is the most versatile one.
Best deving to you too.
