Warning, your game works only on Wavedash: it crashes on itch.io!
Uncaught TypeError: Cannot read properties of undefined (reading 'updateLoadProgressZeroToOne')
You should check the existance of window.Wavedash before calling Wavedash specific functions ^^'
The game itself is quite fun. The heat meter is a nice touch, even if as soon as you upgrade it enough you just can let you finger on the button and there it is. But it's very cool to being able to upgrade our tank between each fight!
Please next time you want your players use their keyboard, think about AZERTY layouts: not everyone use QWERTY, and controls are a bit akward if you think them only for QWERTY layouts.
