For people that want to play the game but are experiencing resolution issues
For anyone having trouble playing it on the game's main page, you could use the direct link to the game (https://html.itch.zone/html/10279936/index.html). I pulled it from the HTML source because I wanted to try it. One reason iframes are used is for isolation for security purposes so if you don't feel comfortable then don't do it.
For the dev
I really enjoyed this one. It took me a little while to figure out what was going on (I initially tried to drag the heart), but once I got going it was good fun. The art style is really nice and the music, too. But what I liked the most was how creative it was. Nice submission!
