Cosmic Seed

In platformer mode:

WASD to move | Space to jump | S while running to slide

If you slide and jump right after you can jump a greater distance

In the overworld mode:

WASD to move | E to enter a level 

The game is still in active development. The platform section has seen the most work, and so it's almost in a presentable state, but the overworld is still very rough and empty.
