Wow, this is incredible. I can easily tell just how much work went into getting this game to feel as great as it does; the visuals, music, level design, everything is so well done! I love the "super cutesy" with dark undertones theme this game has going on (also sidenote but it made me die laughing when i realized the death animation is just peter griffin falling down the stairs lmfao). The tutorial is very easy to follow and the character animations are just an absolute gem; love how each enemy has a unique hurt/death animation (reminds me of castle crashers/newgrounds style flash anims. love it). Also, the amount of enemies and platforming mechanics.. and TWO bosses? my god man. It's incredible you guys got all this done in one week!
Super nitpicky, but one point of feedback I have is that some of the visuals are clearly blurry. I think this is caused by Godot's default linear filtering - a couple of the art assets (mainly UI, by the looks of it?) look "unfocused/low-res"- I think this would be easily fixed by swapping the texture filtering to "nearest" for those nodes.
The last thing I'll mention is that there seems to be some problems with character/bg jitter / blur when the camera is moving on monitors with high refresh rates. We ran into this exact same issue with our game; it's not that noticeable but I would suggest playing around with Godot's physics interpolation setting to see if this fixes it for you!
