Thank you so much for playing and reaching out to me, I've included quite a few of your suggestions into a hotfix that should be live right now that has a big keyboard update that lets you attack with the mouse as well as give a better indicator for the puzzle you concluded the demo at. I made wall jumping a lot easier for the specific method you mentioned as well. Hopefully next time I update the game I'll have a brand new level with your suggestions in mind for a much more free platforming experience.
