I only see a black screen, and some text in each corner. Not sure if the game is incomplete or not?

It's not loading unfortunetly.

I also see a black screen, but I do see the UI, it seems it is not in wavedash either

I tried, but couldn't get it to finish loading here. Bummer, I was pretty excited to play this!

EDITED

ITCH does NOT work on my side I get black screen with GUI 

Game works very good on wavedash

Only thing I have to mention balance of game is off (you are too overpowered -> that way you lose progression).

You are probably too fast -> so only useful upgrades was overheat (not sure why its used) and

repair.

I loved blue mode the most but orange one might be stronger in sense of combat power.

Purple mode is the weakest (cause no spam).

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.
