Was really impressed with the game overall!
I especially liked how the eyes moved around of the player character and was quite impressed with your credits and hand drawn intro and ending splash art!
I did find the enemy ai a little confusing. It was still after me when I tried to use the shadows or boxes so ended up just trying to dodge them. I also found they would often stand in doorways to rooms so I couldn't really avoid them when that was the case. Would've preferred more set routes that they then track onto you from.
Also would've loved to have the footsteps be a better indication of where the enemy is. I think I could hear them through walls which was fun but I'd have loved that audio cue.
I found the bounding boxes hard to use for the energy sources. I often found I could only click onto one side of the energy source and if that was intentional it was unclear which.
But that would only be feedback for making this a full fledged game! Everything I said was very nitpick feedback! Super impressive result!
