Nice idea. As others have said, the tutorial bit was cool but confusing - I nearly quit out before the game already began. Then there feels like there's quite a lot of waiting around (for the jump to happen) - maybe shorten the random duration? And finally I'd have pulled the counter down just above the player character to avoid always having to flick eyes up to the top of the screen. Otherwise good job, I like it
Thanks for the elaborate feedback :) yep, that timer definitely needs some tweaking, both duration- and designwise. I really like the concept of another, similar game from this jam, it has a fixed timer, but the "running out" is conveyed by the player contracting like a spring and then jumping afterwards. I'm thinking of something similar for the post-jam update.
