This game is difficult. I wasn't able to get many of the keys and the monster's fast. Even with the bush, I wasn't able to avoid it enough.
This is alright for your first game jam ever. And especially for a solo developer.
Also the game wasn't working properly for me in the web build. It was cropping and I couldn't see the full picture. I had to download the ZIP file. Windows Defender was also falsely labelling one of the script files as a Trojan virus and it kept auto deleting the file. I had to let Windows Defender allow your file in order to scan it with other antiviruses, which felt a bit dangerous. I'd make sure this isn't an issue in the future, so that more people can play your games.
