Nice concept and little game😊! Also very neat that you use your own framework to make this game 💪!
GAMEPLAY
Good concept with the timers and the other realities when you die. I needed some practice before I could manage that mega jump very well. Especially in the underworld it is hard because you are upside down, but is also a nice challenge trying to manage it in time. Fun to play.
GRAPHICS/ART
Simple but effective and nice pixel art! Some extra effects would have been a nice bonus or some extra variation in environment and enemies.
AUDIO
A good 8-bit or frantic audio track would have fitted this game nicely. Maybe in an update or the next jam you will manage to add some extra audio/sound/
THEME
Nice idea with the changing realities and also with the timers. Checked the themes.
Overall a very nice little game. Keep up this good work💪!
