I'm super happy you took the time to write this, and thank you for playing! :D
swoopie has already been so kind to respond to some of you concerns, but I'll try add some dev perspective as well.
You are fully right in your criticisms because the game is lacking good UX in big areas, but I'm sorry to say that most of these will not be fixed in this incarnation of the game, because it's made in pico-8 which has hard restrictions on code length so to add stuff something else has to be removed. Anything You think is superfluous?
The misclick escape is another thing though. Because you and others have had this problem it'll end up high on my todo, and thanks for the suggestions!
Also, since you mentioned building own levels I'd like to mention one of my inspirations: the Castle Doctrine by Jason Rohrer, dont know how active it is anymore but it's worth checking out!
