First, thank you for the kind words, I'm glad you liked it enough to write so much! I also get the feeling of "I would change this" when playing games, so maybe mine will inspire your too! If some things seem simplistic, originally this game was supposed to be a 2 week project. I just kept working on it for 5 more months and it got somewhat bigger :D. The bug reports really help too, I will have to look into them. Im not sure I understand the first one though was it this event?
For the Closest Distance I actually used to do a distance check but I wanted the front row to always be hit first, so I changed it to be explicitly: Hit the enemy in front of you first, if nothing there, hit the space above that, if nothing there hit the space below that. If theres nothing in the front row, it does the same check but for the back row. This way its predictable and always the same, even if I move things around.
