YALAXY01-Yearlysis by MysteryStrawberry is an action game and is a submission to the GBA Jam 2022.
The game resonates ‘boss-rush’ style but its less likely to be made like that because the developer is still working on the process. You play as a robotic alien creature. You can slish-slash your way through the foes. You can also teleport to different time places and portals and use your cycle colors for defense.
