The game was stuck on the splash screen. Tried to play it on chrome and Firefox but to avail. Seems like its just me because no one else has mentioned it. Once the jam is over, can you provide a executable as I definitely want to play it.
Edit: Got it working, thanks to the dev.
Gameplay is really fun, I like how the pace of the music picked up as the lava started rising. Really liked the colours you choose too, the compliment each other well. Overall, the concept is really good and execution is just as good.
