Thank you so much for your feedback, I am really glad you appreciated the game's atmosphere.
As for the assets, I've spent a lot of time looking for them or modifying them to fit them into the game. (using gimp, aseprite, audacity and other software) Maybe in a future jam we could get an artist on board, but since this was our first jam ever, and we did not want to hinder anyone's project, we decided to go into this direction and do our own project.
Thank you again.
