Thank you! I'm glad you enjoyed it :) The guards were a little faster in the early versions, but i slowed them down so they wouldn't be as difficult so more people can beat it, but i completely understand where you're coming from. Slowing down just gives you more time to think :) As for the light switch, i'll probably make a bigger and more noticeable sprite if i ever work on this again. It was kind of a last minute thing i added to make it a little different compared to the other 2 levels.
Thank you again for playing :)
