Oh boy, it took me way too long how to figure out how to play this. I seriously spent about 10 minutes just walking around the opening area before I realized where the light switch was. Could definitely have used some kind of light on it maybe just so I knew where to go. I have to say though, the presentation on this game is fantastic. I absolutely love the lighting effects done in pixel art. Really gives the game a magical feel! Overall the puzzles I'd say weren't terribly fun in their current design...the only one that seemed to have a solution for me to figure out was the last one where I had to realize where the light switch was to turn on. It was a neat discovery to realize that you could slow down the enemies with the crates! I'm not sure I ever used that one to its full potential though. The conversations with the boss were super fun. Overall a great game!

Thank you so much for playing! All valid points and very reasonable. Definitely could've put a light on the first switch, but decided against it cause it sort of had a light on it already and i understand it blended into the wall quite well, but figured when you find it it'd pay off :p The first 2 levels were there to teach and the 3rd and last was more of a puzzle. I wanted to make more levels and add a bunch more features, but ran out of time cause i wanted to polish what was already there. I found out you can use the crates to speedrun as well by watching one of my play testers haha. He was pulling the crate and one of the guards was pushing it.
Thank you again for playing i'll definitely be checking out your game when i have time!
