To exit, press Q - the gray screen turns on. I understand that what you did for the PC at first, then made a build for the web.
I liked the music and sounds. Reminds game of worms.
We have a similar game but in the game :)
Hi. It's Q for controls when in the game, and Q to exit when in the menu (perhaps not the most logical). I didn't make a PC build just a WebGL build. Thanks for playing! :)
