Nicely polished visuals and music, getting some Captain Toad Treasure Tracker vibes!
Levels can be skipped directly to finish with very little challenge, wouldn't it be better to require collecting these Dragon Eggs?
Controls need improvements, placing blocks is quite clumsy, especially on top of each other, no way to slightly adjust positions on sides as there no ability to rotate the camera, also switching two modes with mouse and pixel perfect clicking on thin sides to scale is meh.
Blocks falling into the water and not respawning is not a good idea
