This is my entry for Mini Jam 107, where the required limitation was "gravity is under your control". If you run into slowdown on the web player, you can try one of the native binaries below (or the .tic file if you have TIC-80).

Default controls (assuming keyboard or Xbox controller):

Keyboard	Xbox	Action
Arrow keys	D-pad/Left analog stick	Move left/right
Z key	A button	Jump
X key	B button	Switch gravity
A key	X button	Shoot

You can configure these controls by pressing the Escape key, then navigating to "options", then "setup gamepad".
