I really like the progression between the levels! I did have a problem where it only rendered in the top-left corner of the screen, but other than that it was great!
ah what's the issue with the rendering?, i had so much issues with the viewport when it came to exporting it to itch ( ̄ヘ ̄;)
yeah getting web builds to work can be a huge pain. For me the entire game was scaled to the top left 1/4 of the screen and the rest was blank
