Thanks, glad to hear it! That was actually one of the criteria I had for deciding on a concept, aka. "The prototype for the game has to be fun as well".
As for a download: Not right now, we don't want someone playing the full version to affect the vote on itch as that wouldn't be fair to the rules if we haven't got permission to do it. You can bet we're gonna upload the second the jam is over though! (Well, as soon as we can ;) )
