I remember playing the original game this summer during the HPS1 gamejam. The game progressed a lot since that time, congrats on that ! I don't know why but it reminds to me the era of flash games in the early 20's. Those games were often really strange and I think it's interesting that your game leans toward that.
The game is still hard has nail but more balanced than the old entry. I noticed that sometimes enemies not killed and off the screen can still shoot me, don't know if it's a bug or intented but it's ads a lot of tension to the fights :) Keep it up !
