I see the problem. In this example if you press 1 the spring should fire and your pirate will walk on the trees! Thank you for playing! We have completed 30 levels without fail.

Most of all, I'd display the controls at all times - ideally showing them in combination with the obstacle it controls (so you know what they look like). Ideally there should be a short tutorial level with one of each obstacle and you have to press each of them to make it, with a moderate distance between each obstacle and failing if you don't press it. I'd definitely try to make the controls more responsive too. And lower the volume of the music a bit. But great work - procedural generation definitely helps with making longer gameplay, and I wish I had time to do something like that for my game.
