Totally Tubular

Built during the Global Game Jam 2025, on the theme/keyword of bubble. 

Inspired by the different gas mixes used in diving, this game has you keeping the right mix of air for the diving bell at the end of your line. 

Instructions:

Using the arrow keys or WASD to navigate your way down the umbilical. Make sure to keep the gas mix right for the depth your at. As you get deeper, make sure you have the right mix of Helium, Oxygen and Nitrogen. Progressively adding more and more Helium as you descend. 

Don't add too much though, getting your gas mix wrong can end your run very quickly. 

Warnings are provided when your mix is off. Yellow warnings mean you have time, red you're close to losing. Additional warnings are provided for when your mix needs to change. 

Controls:

W/Up arrow: Move your bubble up. 

S/Down Arrow: Move your bubble down

A/Left Arrow: Move your bubble to the left

D/Right Arrow: Move your bubble to the right

Escape: Abort your current run and restart
