Hello Everyone!
Abysm is a physics-based puzzle game, inspired by classics such as Boulder Dash and Supaplex. Explore the catacombs of Portsmoor, uncover the secrets that are threatening the town above, and save both yourself and everyone else! The game has handcrafted pixels, atmospheric music and sound, a simple story, and a lots of fun puzzle challenges.

I've just updated the demo here on Itch, but also released the demo on Steam for those who find it easier to download from there:

As a bonus, on Steam you can easily download and play it on the Steam Deck, which I would recommend if you have one. Please download, play, enjoy, and wishlist the game on Steam! :-)
