Problem: the game doesn’t fit on its own canvas:

(Running Firefox on Linux Mint, 2160p resolution, no scaling.)
Hello! I've read your comment and sadly, I have no way to fix it in browser, since the browser version was made for Android, while the downloadable options were made for PC. I probably should've mentioned that in the game's description...
I recommend you to download the zip of the game if you're playing on PC, rather than playing it on your browser.
Hope this helps!
