Really enjoyed this one. Love the idea, and your execution of the growing/merging mechanic. The difficulty in the challenge mode felt like it had a decent curve to it, which is always super impressive.
Some small notes, incase you're looking to update the game:
- There's a bit of UI jank on the exit button, it seems to push the start buttons around when you highlight it?
- I had a little trouble moving around buildings, as things got more dense. In the sense that buildings covered other ones, so I had trouble clicking them.
I'm not entirely sure what you could do to help the control issue. Allowing camera rotation maybe? The top view helps, but I found myself not wanting to use it, because the isometric view just felt better to look at.
I loved seeing the new building types as I managed to reach a new highpoint, and the chill music and the pop-up sounds were lovely to have in the background as well.
