Thank you! Although this version took way more than 2 hour, only the first draft was 2 hours, and can be listened to here https://2hac.bandcamp.com/album/monstrous-2hac-volume-19.
Indeed, the challenge is a lot of fun, there is a dedicated website, https://2hac.abstractionmusic.com/, and also a specific jam based on songs created during the challenge here https://itch.io/jam/ost-jam-v7 (and it is live right now!)
