A stunning game presentation wise. Very fitting sprites and music.
I could not figure out how to regnerate the currency after I spent it on some buildings. After that the game didn't seem to progress anymore. An introduction (if not in game, because that stuff takes a lot of time) on the page would have been helpful.
I noticed some minor things.
- The reflection in the water is not properly synced. The more the character goes left the more the reflection in the water lacks behind. Maybe you changed the scaling of the render texture and have not compensated?
- I noticed some flickering of assets at the left side of the map.
