The soundscape in this game felt very creepy - there's a good choice of background effects and ambience.
As others have stated, it would've been 100x better if you would've used art in the form of pre-made assets, or even just some quick doodles, instead of generated imagery. But I understand why that might have been the only viable option at the time.
Overall, I really appreciate the effort that's been put in the game in spite of the constraints. Keep making more games!
