One of my favourite games released in 2025, BALL x PIT from Kenny Sun and Friends / Devolver Digital has sold well enough that it's getting free upgrades.
Cannon Fodder is a retro action-strategy gem from 1993 that was originally released on my old love the Amiga, and the modern open source port just got upgraded.
Tingus Goose has released recently and after being mystified by the demo, I took a look at the full game and I honestly still have no idea what is going on.
Riding the wave of more cozy games, developer Dry Cactus (Poly Bridge series) is working on their next game titled Poly Bricks that will come to Linux.
