I would definitely play more levels.
I forgot to add a suggestion on the button thing, which is to add a blue/yellow conduit leading from the button to the door, which lights up in that colour when you press it. That would clearly indicate that the button is now in a "pushed" state, and didn't simply have a one-time effect or required both to be pushed simultaneously.
Good idea! I was thinking that I could have been more explicit with a real spotlight + a sound related to the light, but a visual relation with a wire that change state when the button is pressed is a much simpler and direct approach, I like it.
Great feedback to polish the first level with all these ideas, I'll take that approach for the new levels also =)
Thank you so much!
