Yeah you did a really good job on the AI. Thanks for explaining it.
The taunt may not be there, but it was listed in the controls menu, that's why I thought it's button does something when it probably didn't.
You may have overscoped, but sounds like you learned a lot so maybe that scope will be fine for the next one :)
I don't have any jump tutorial unfortunately and I'm also struggling with that part in my games, for my next one I plan on spending a fair amount of time making sure it feels right before moving to anything else.
In terms of the art, I really understand how hard it is. What I did for my game is look at some tutorials and references and try something very similar. Then while working on the game I was able to spend a lot of time polishing them and they became more unique, while I feel like I also imporved a lot from this process.
As a non-artist pixel art was much easier for me, maybe you can start there.
One thing I forgot to say in my original post was that the sound was not playing at the start, and that was because it was turned off in the options by default.
