Very nice little game, art style and vibe is good, and its a fun idea to impersonate a rampage demon. You say its not fun but I think it is, to me it has that satisfying and addictive feeling of "mowing the lawn" which reminds me of vampire survivors, i.e. effortlessly destroying everything and collecting tons of stuff. You could maybe tweak a few parameters to increase that vampire survivors feeling (if you want to go that way of course) : for example increase the spawn rate by 2 or 3 or even more, pick organs from further away (or even attract them), kill on contact (no more spacebar), etc. Sorry I dont mean to pretend I know better, I could be totally wrong, I just think the game is quite fun and you are underselling.
