Gave the game a brief spin on my Steam Deck. Game ran great, looked great. Love the color palette. Similar to the apogee HD games Emberheart did.
Issues: controls are way too slippery. Getting into the mansion was a chore.
The biggest issue though is with shooting the zombies. The shotgun blast only seems to do damage when the far edge away from the player connects with the zombie. When the zombie is close nothing seems to happen.
