Tried to play it but I keep falling after this point and I'm not sure how to proceed.
I tried to keep the resolution small because if it was any larger the game would break
Was that in a full screen?
It may be the resolution of your monitor
Ah yep zooming out in the browser to make the game small fixed the issue for me. I have a high DPI screen.
Nice game. I like that it gets more challenging over time.
