This is a really cool setting/theming for a game. The backstage crew is really the most interesting part of a production, so a puzzle game involving that has a lot of potential. I like all the charm you’ve added, too - the actors’ personalities, commenting on the dodgy script, etc. It’s very fun. I like the music a lot, too - great medieval vibes, and the way the character cue instruments integrate into it is awesome.
I think the gameplay itself could be improved. The puzzles are never all that complex, and often boil down to the game telling you exactly what to do, or just kind of guessing. This isn’t the end of the world, since the game is mostly about the story and setting… but if you get something wrong, the game makes you do the entire thing again, which really takes me out of the immersion. (There’s also a bug of some kind where if you do everything too fast, the game gets confused and stops showing you the instructions… so you can’t even speed through it after a failure.) I would suggest making the puzzles a little more engaging - there’s a lot of material in this backstage crew setting - but if you’d prefer to keep it simple, at least don’t punish the player so much for turning on the wrong light one time.
Nice work overall, a very cozy entry!
