If I was you, I'd update description on google play to something more descriptive

So I think I have settled on solution shown below ( for the building window ) although I would still appreciate your input.  The other thing, I tried working on font as suggested and I can't seem to find an easy way to match pixel size with UI... The issue is that I change font and it is created by unity rather than drawn on a sprite... I will look into other free fonts later when I come back to polish it a little bit more

Also threw together a quick view of a mission selection window, it looks simplistic, but I kind of like it would love to hear what you think

And sorry for potato image quality, I should write a script to screen cap the game view -_-

How about having the starting level (0 or 1) to the left of the bar, the max level to the right of the bar, and the current level inside the bar, if it's greater than the starting level but less than the max?

Regardless of how you do the text, I think you need to find a font that'll let you have text that has the same pixel size as your artwork. It looks bad as-is.

Yeah would be cool if text was the same pixel size, right now I have like 32 pixels per unit of measure on UI so I have to some how either work out the font size or just make my own, would be easier if game didn't need any font '-_-
But yeah gonna work on that, didn't notice it myself.

Regarding the way you suggest marking it, I did think of something similar today, gonna give it a go tomorrow and we will see how it looks
Also the progress bar doesn't suit the style too well, I tried making something like bar out of blocks (for example like minecraft health bar but only in full blocks), it needs coding because when it comes to pixel art, unity is very fussy with core features that would let me do that and stretches the pixels.. So either I work this out or just gonna code my own progress bar made of separate icons.

Finally the Xmas craze is over and I can continue on this project, happy holidays by the way!
And thanks for the input, much appreciated did a lot of games through out the years and I am just not gonna give up on this one and fulfill my dream of publishing a game:)

Dug a little bit and the game that I remembered was "Pirates! gold" from 1993

Art critique aside, god damn it I love it - reminds me of some old pirate game where you drove ships to Tortuga and such, boy what a punch of nostalgia... On the art side I too find exploration part lacking detail in some places ( some things are detailed and others are not ) but that is just my amateur look
