Fun game for a few hours. Then you've unlocked all the buildings and there's not really much to do anymore. You can still unlock more numbers and upgrades but there's not much point/motivation to it and the gameplay becomes fairly repetitive.

Since the upgrades give constant additive instead of multiplicative increases, they also don't really feel impactful at that point anymore. Especially for the machines (adder, multiplier, etc.), the slight speed increase hardly matters since they are free anyways so you can just build slightly longer rows with a few more of them. I stopped upgrading them once I got to 0.5/s since that made the ratios very easy to calculate and the upgrades up to that still reduced the number of machines needed to produce full belts by a fairly significant amount. The belt speed still feels a lot more relevant but it still isn't that motivating to work towards a 15 or so percent improvement compared to the early upgrades.

I also don't really get the point of belt priorities and storage (the last unlockable building). You can just build as many machines as needed for the correct ratios (or more) for free. Though seemingly unlike most other people, I did find the subtractor somewhat useful, since there are a few numbers where it's much easier to multiply to something higher and subtract something simple. But also never used the divider.

Overall, those thing's don't really matter/change much though, you can just ignore them and they wouldn't make the long-term gameplay more interesting anyways. Either way, it's still fun for a few hours which is fine for the price.

Edit: One more QoL thing that would be quite nice is if we could drag belts diagonally and it would automatically create an L shape of belts.
