Answering all your AI claims that is not much help for me to improve the game.
I do agree that controls are a bit weird, trying to press 123 quickly while using WASD, As a left-handed person who uses arrow keys, I see where you (probably right-handed person) are coming from. And get the game idea correct next time, you don't press "shift" to stick on walls.
The game is not a pixel art, that circle is very much a perfect circle, unless I'm blind. If you are insulting the sprites, I'm not the one that created it. The soundtrack is long enough that you will never reach to the end where it loops, and the soundtrack is pretty much your opinion you can mute it in the settings.
Don't really get this claim, the game is actually hard, got many people complaining that it's too hard. I added a leaderboard system to give some sort of motivation to keep playing, you can count that as a hook.
There are bugs, yes, but it won't stop you from playing the game or completing it.
Yes, Shapeshift deserves your time.
