I liked the aesthetic that you created. I liked the graphics you used and the parallaxed background layers were great. The movement and the jumping felt very smooth and intuitive. I really loved the effect you created of the intensifying TV static every time you collected one of the items. I thought the ambient rain sound was a nice touch as well.
As others have said I think you could benefit a lot with simple things like (perhaps) a sound for walking, jumping and collecting the items. And then perhaps a simple mechanic like when you collect all the items a weapon spawns and if you collect it and press 'e' at the right time you banish the ghost and win, kind of thing. I appreciate how difficult it is to get everything done in just 7 days though and I think what you submitted is really good so well done.
