I collected everything except the last bomb and time ran out when it was right in front of me. Anyways, here's what I think. Keep in mind that my review is going to be biased towards what I like to play.

First of all, there is a weird delay when clicking on button in the main menu. The intro is kinda long. All the player needs to know is that there are bombs, city gonna explode, mayor gone. Writing is not really my thing, so I can't say too much other than to make it shorter.

The map is way bigger than what I would prefer. I like how you have a center piece for almost every part of the map, but is there really a reason to split them out? I spent most of my time running around, so I would cut the 'boring' parts out and make only a  couple of maps, with multiple of those center pieces in each map. When opening the map, it also took me some time to find where I'm at. Consider making the indicator more eye-catching.

Controls are simple and straight forward, which is always good. There are some nice details like making the roofs transparent to not hide the characters, and making dragoons react when bumping into Doki. Dashing feels nice, but it doesn't really serve a purpose since there's nothing to evade. If it's just a matter of making the player move faster, then maybe the stamina bar is not needed.

I've got to say that this game is much better than the first few that I've made. Great job working on this and looking forward to see what else you'll come up with. (Also, the secret is cursed)

Cool game! I enjoyed exploring the city and finding all the easter eggs.
