Eggvania

a and d for horizontal movement

w for interacting and upwards attack

s for downward attack

k for attacking

hold c to heal

space bar to jump

e to dash (you get it later in the game)

White rectangles are either chests which you can open by hitting them or respawn points which you can use by pressing w while touching them (you won't see anything but if you die you will respawn there).

Collide with collectibles (hexagons) to collect them.
