Do you remember Kuru Kuru Kururin for the GBA?
A tiny bit of post-mortem:
Adding part of Kururin's main mechanic into the game was what made it work for me.
I didn't intend it this way at first, but the moment it happened I just couldn't look back. It made everything in the gameplay and the maps come together.
Having to balance the brute dash mechanic with the careful crawling through tiny-spaces makes for the right amount of easy-to-grasp-hard-to-master essence in this game. I hope the 6 levels I made are able to highlight this.
It's always interesting to see your own game grow organically during the jam. And this is why I participate in these jams.
