Lunistice - 3D platformer
Post artwork by gears2gnomes
Lunistice is a 3D Platformer created by A Grumpy Fox, with a cute PS1/SEGA Saturn inspired artstyle in mind.
It is available in Steam, GOG and Nintendo Switch, and has a platinum score in ProtonDB.
I enjoyed it quite a lot, and with a new big update in the works, I think you should check it out.
