This is pretty fun! Challenging but achievable once I start getting used to the mechanics (though sometimes I do just brute force it then it works xD). Like what CrispGalileo pointed out before it'll be nice to have a join button, and maybe some recommended shapes for what might work better for earlier levels so players can learn and explore as they go on. But great job to make this in 48 hours, I see great potential for this:)
