As a fan of horror games, I really enjoyed seeing your take on how to incorporate those emotions into a shoot 'em up. Great use of pixel sprites, I especially like the animation of demons crawling across the floor to you as it made me feel really unsettled. Your desired mood was strongest in the first round of play. Feeling enclosed in this small linear gameplay loop while having hoard of enemies worked well. Coupled with the droning ambient background music. To make the experience even stronger in the next levels, I would suggest amping up the background music and maybe adding different enemy types during the "frenzy" phase. You could even add some animations to the forest or make it so that colliding with the trees is harmful as they too could become "demons" This would make the game feel a bit less repetitive as well and lengthen player interest. All in all I think this was a spooky little game and I'd love to see you continue making games in the horror genre.
