Pretty fun! I love this style of game it reminds me a lot of binding of isaac .
A couple of issues I found:
-when going from a north room to a south room I naturally want to hold S so that led to me running into some spikes in a cross shape before I could even see them!
-There was one point when I walked into a room and there were instantly 3 slimes boxing me in before the camera moved to the next room - I think this was also due to me being able to keep running further into the room during the transition.
The movement and shooting feels good though, and I like how when the enemies run into you you get slowed down, it makes it really punishing if you get yourself into a bad situation.
