Overall great game mechanics. Art style is very reminiscent of what it is tributing. It has the tiny towers characters which is great. 

What should you keep doing: Providing more types of blocks. You would only see a set value of blocks however the more you play once you unlock the more tiles you see. Maybe unlocked once you place them down. Show what you collected in the summary screen.

What I want to see: Better detail in summary screen. More progressions of unlockable things as you improve your score. New alternative designs of blocks. Mobile compatibility/touch screen friendly (have not tried this on touch screen 02.22.25). Progression save system for each player or at least, each instance. 

Audio settings: adjustable audio settings accessible anywhere in the game.

Maybe honestly continue storyline once you reach a certain distance this would trigger a cutscene and a break for your hands then a longer goal to reach. More of a visual checkpoint/goal as you progress along the game. (This could even be another mode like story mode) and you have a classic mode. 

Another mode where its a puzzle instance: multiple set 5 blocks you need to place and its a predetermined already set building so placing correctly will solve the puzzle. (see chess.com, learning examples).

Overall great game!
