My short and sweet Puzzle Platformer game is finally finished !

I made the first version of this game for GMTK Game Jam 2021 on Itch. I reworked it from the ground up for a few months, and now it's a full game of about 3 hours.

You play as a cute key. You must find other keys to open doors on the way, but each key makes you heavier and lower your jumps. So you must choose wisely which key to pick up and when.

if you just want to have a quick look, a free demo is also available : https://yorsh.itch.io/100-keys-to-your-heart
