Only one... Plumbus? I suppose this product is the tool of the future, but the way the game played, it felt more like there was only ever one option. I enjoy clicker-style games, but this one is honestly not very well done. Accumulating assets feels slow, probably because the resource progression has been artificially adjusted to make the game feel longer. And it never feels like there's a meaningful difference between upgrades, so I found myself always buying the cheapest one. I also encountered some bugs with the cash per second display value, but that's unsurprising given the time constraint. It is a creative game, but more in the "lol I'm so random" way than in any exciting or meaningful way.
