I've recently created this mini game where the player controls a critter with 4 individual tentacles - the catch being, those tentacles only shoot out diagonally, so the player must move the critter around using a game controller R1, R2, L1, L2 or keyboard inputs.
It takes a bit of getting used to, however once you master the technique, it's really fun crawling and slinging yourself around to collect matter, trying to survive as long as possible.
Well, that's how I feel anyway... curious to hear what others think? Have you had similar issues? Players giving up because the muscle memory is too strongly linked to familiar game input / controls?
You can test it yourself on itch, Controls and Items are described on the page, might be worth reading before jumping into the game: https://add-soul.itch.io/crawl-critter-crawl
