Lovely game, it will take me a few tries to get through it. I did have a graphical problem with the screen because I have an ultrawide (3440x1440) and your scanlines graphics don’t quite go far enough so I occasionally got hung up on the right border of that.
I did miss a few of the side doors because they weren’t obvious to me.
I thought the controls were really smooth (using a controller) though I couldn’t select settings when I first went into the game (I had to use the keyboard to get there).
Fun boss fights, ramped up rather quickly. I’ll beat the boss, but a fun loss.
