Well done game! Explores the pillar scaling mechanic in a good variety of ways. Even if it’s relatively a simple thing, just seeing the horizontal pillars for the first time I found cool.
I do think some of the later levels were a bit too mechanically challenging, though. They made great use of the mechanics but their difficulty could perhaps be toned back a bit, perhaps by adding more frequent checkpoints.
Besides that criticism, though, an extremely well made game! Great job!
