Took me some time to get to this submission, but I'm glad I did! Very polished entry with crisp and precise controls, proper game feel, scary monsters and nice sprites (pun intended xD). Music was spot on, action felt very action-y, and the idea of upgrades having a downside was interesting. Seeing so many games with a small area to play in (that in many cases shrinks as well), it feels a bit old already and restricts the player movement a bit too much in my opinion. A good fix for this would be that maybe in the beginning the area size would be full screen, and would slowly shrink as time goes by, so you'd have to kill enemies as fast as possible. Just a thought, though. Overall, I had a blast and this was very fun!
We'd appreciate if you had time to check out our submission as well! :)
