Thank you for your constructive feedback, I really appreciate it.
Nearly all of the mentioned issues will be resolved, except for the inconsistent pixel art sprites. I can't do pixel art and it would require me to hire someone else to fix these.
I plan to release an update with all of these quality of life changes a bit later since there are even more improvements that can be made that were hinted by other players outside itch.io. And I want to tackle all of them with the first update.

You can drag and pan the map with the middle mouse button.
And most maps don't have standard victory conditions.
