Excellent game. It scales really fast, or at least quickly enough to keep introducing new mechanics just as I was getting bored of the current ones.
The music really comes together: I really did not expect it to sound so well.
However, it has one glaring issue: performance. After just a couple minutes, the game starts suffering lag spikes every few seconds which last way too long to be bearable.
Also when such spikes occur, the tick timer keeps advancing but items on pipes do not, with the result that a carefully timed setup is completely screwed, and a dozen item bubbles stack on top of each other.
This ended up being a deal breaker, as I quit after making a 1M per second gold microchip.
