The prices seem promising, anybody knows anything about these accounts who made the game jam, are they trustable? I wouldn't want to spend 2 weeks on a week just to turn out to be a scam. I am not sure if its common on itch.io or not but I am skeptical. 

Hello I am Qwibble, a lead dev for team quimbly, I take it you aren't on the team quimbly discord? I highly recomend you join and talk to our community if you're uncertain as o our authenticity :) --- Hopefully you'll choose to join the jam :D

Thanks, I will check it out.
