I just noticed you somehow made (and/or contributed to) multiple titles in this jam. That's incredible.
This visual style (with the low-red 3D backgrounds and the relatively detailed pixel art sprites for characters) works great and it's something I'd love to see more of. Very smooth animations too. Gameplay-wise, there's not much here yet as you've said, but it's very promising as a prototype.
Also, thanks for including a Linux build!
