I have submitted the game to speedrun.com, just need to wait and see if it gets verified, i just used a casual run for the verification run, i didn't do it too quickly, i think it was like 8 minutes or something (i cant even remember what the time was even though it was just yesterday)
It's been verified! Here's the link to the speedrun.com: Gun Slime (itch.io) - speedrun.com
(The page is a wip, i need to finish some small things, like a banner and an icon for the game)
