Thanks for playing! Good to know some people don't mind the controls. I think there are still improvements to be made, but it'll be largely like it is now.
For the ladder puzzle, I bet the problem is that the game never tells you that you can shoot the target again to deactivate it, and at one point you need one active and the other inactive. I should probably explain the buttons over multiple puzzles so players know they can do that.
As for that ladder, I'll push it more upright, and I should probably put collision on them anyway, since the only reason there wasn't was because it was causing problems if the player was on the wrong side of the ladder.
