Hey :) Thanks for playing! I really appreciate the kinds word and for playing my game.
That level was the final level, so great job getting so far ;) It's a bit of a tricky puzzle, and SPOILERS, but basically you need to push the box onto one of the spikes, then pull the lever. It stops those spikes coming up so you can make it through. I was worried about that since I never did any real tutorial for it, but thought it would pose as a good final test. Perhaps not haha!
Thanks again for playing :)
