Beautiful art, animations, music and sound effects and felt pretty good to play, Though I have some suggestions and some bug reports.
The perspective of the game looks nice but is kind of annoying to move around at times with WASD because you constantly slam into walls because the angles of the walls arent perfect diagonals so you can't really go straight in any direction or diagonally, you have to hold left/right and kind of press up/down occasionally.
You can walk around in the void and inside of the walls if you either defeat the boss and playing again or if you try to kill yourself by using up all your health by spinning webs.
You can get absolutely boned by the boss if you don't have enough web when entering the room aswell and I feel that the web-spinning could be used a bit more interesting, because sometimes you just have to kill yourself to proceed but if you use all your health to spin web you break the game and can walk anywhere.
It would also have been nice with a damage indicator either with just a hit effect or damage text, also the red piercing upgrade seems a bit broken as in it doesn't seem to work properly and won't register hits a lot of the time.
