Fun ⭐️⭐️⭐️⭐️⭐️
Really cool gameplay. Very intuitive, and exactly as long as it needed to be for a gamejam. Great job! The only feature you could have maybe added was a previous-run track or something to more easily know where you should place a block, but the difficulty is low enough it didn't matter much for this demo.
Theme⭐️⭐️⭐️
A lot of games chose the 'build to "scale" up' approach which I'm not a huge fan of, but this is one of the more interesting approaches.
Style⭐️⭐️⭐️⭐️⭐️
Really excellent, polished art style, and cool theming.
