A small environmental/playground Knytt Stories level I made rather quickly (for me anyway) using an idea I thought would suit the 2021 KS Un-epic Level Contest but ended up not using there. It's a very short one, although it features quite a lot of hidden secrets to be found, including a tiny special area you can unlock by collecting all four keys.
You can also play it in Knytt Stories Plus to enable a bonus collectible that doesn't unlock anything but looks kinda cool, if that's one of those things you can never have enough of!
Made over lunch today using Kool Tool. http://ragzouken.itch.io/kooltool
Somehow anticipated the rest of the day...
Windows & Mac builds included & Love2D file for Linux users with Love2D.
Play the music file in the music player of your choice then load the game.
