Hi .. as promised I played and rated your game. Now the review :)
What I loved
- UI / Pause - I love that you can change res option and the volume/fx slider are there
- The concept is cool .. binding of isaac style which is a winner
- Enemy follow is also very good , not too intrusive, looks natural 'stalking'
- Colours / pallette and ambience are really nice
What I would improve (in my opinion)
- Background and sprites have a different style. The background is linear and clean and the spreites are doodle style
- I would make the player squisher leaving particles behind him when he moves
- When player is hit, I would make a visual key - change of colour , a sound .. your choice
- Personal opinion - For game jams I would do a Webgl / browser build. There are over 1000 games and people might be put off with the download sequence.
Overall , great submission! Cheers.
