I've played through and I had fun collecting those small guys!
I kinda wish there was more combinations - a big majority of the ones I've tried didn't work, and ultimately I managed to find, like, three. I assume the button "Collection" in the pause menu that didn't work for me would reveal recipes for hexagons I've found, giving me knowledge of how to craft those high-tier ones, which would be super cool. Not sure if it just something that broke for me or you've hit a scope creep and haven't been able to properly implement it in time 👀 Either way, I managed to hit the quota before trying more combinations (spooky ending btw, won't be able to sleep at night now).
Apart from some technical issues (not recapturing your mouse after user unfocuses the game, not being able to skip through cutscenes in caves which gets quite annoying after going through them like 20 times, and well, the aforementioned collection menu not functioning) it's a quite cute collectathon mini-game. Nice work on your first game jam!
