I already did, it's on your game comments section! Thank you for playing my game, though. And yeah, the initial plan was to not give the hints, but I was afraid it was going to turn off a lot of people. I really like games that don't tell the player what to do, but by experience you need plenty of carefully planned levels. If I had people to playtest it and more time... You can post that on my comments section too, so that other people that are the game read that too, that's good tips overall.
Oh right, sorry I didn't realise it was you ^^
I totally understand why you put the hints, especially in a game jam context, you'd want as many people as possible to try it out. I kind of regret not having some in our game, I think many will give up without seeing much. But maybe you can find a way to "teach" the mechanics without writing the solution on the wall through gameplay, or ask the players before they start wether they'd like help or not. Or deliver the hints only after a certain time has passed. As you say, having lots of playtests would help find the best solution!
Sure, I'll copy it in your comment section then :)
