Cool artwork but don't forget to add sounds to your game. Gameplay is fun but enemies which jumps from darkness in front of player is too annoying. Thanks for sharing!

First off, nice sprites. I love the unabashedly goofy premise, and I always like playing a villain or creepy character. :) 

A few suggestions for improvement: 

1. Sound! It really adds to the immersion. You can use programs like bfxr to generate old-school bilps and bloops. For music, you can borrow from a free-to-use collection (assuming you are unable to partner with a composer).

2. The enemies should flip to face the player. In practice, this simply means: If the player's X-coordinate is lower than the enemy's X-coordinate, set the enemy's scale to (-1, 1, 1). Otherwise, set it to (1, 1, 1).

3. A greater variety of enemies would help keep things interesting.

4. The text size needs to be larger, relative to the size of the game area.

Game is a bit too easy for my liking, but pixel art looks really good animations are nice and the kight effects look cool.

the concept is interesting especially the idea of collecting eyes to illuminate the area. Kudos to you!
