Razing Core for the Sega Master System (Bad Computer/2026). New vertical shmup for this classic 8-bit console. With 7 stages, primary, secondary and Core weapons, large bosses and more, it offers great gameplay and reminds me of the Aleste series. Physical release is planned for 2027. badcomputer0.itch.io/razing-… #gamedev #Sega #8bit

Official physical editions of my Master System games are planned for next year — made professionally, as with Frontier Force. I will announce specific titles, and where to get them, as they are confirmed. Thank you again for all the support! #mastersystem #homebrew

In the next version of the itch app you can... make your itch games show up in Steam 😅. This has been a long outstanding request that should make it easier to play your itch games without having to change apps on Steam Deck or Big Picture mode

Final beta testing for Till & Hat has been underway this past week, and I'm pleased to say the game is perfectly compatible with real hardware from start to finish. Of course, plenty of plain old gameplay bugs were found, but the list is getting exhausted by now. Almost there...
