It's just okay. It's exactly what it looks like: another short mindless 2~4 hour "easy low-dexterity timed minigame -> spend currency on node upgrades" game loop.

If you go in expecting and wanting that, the game loop itself genuinely succeeds at delivering mindless fun.

If you want anything more: I did say it was okay, and I'm rating it overall positive, but... maybe skip this, because as is par for the course for these, there are many sloppy/arbitrary-feeling pacing and balancing decisions.

...such as....

• There's a prestige system... but it's very shallow and you'll end up beating the game after only a single prestige before feeling the need or desire to do another. (you'll buy 4 upgrades on your first prestige, with absolutely no decision making (it's all you can afford) and start over with 2x fuel + 2x damage + 2x income)

• The "boss asteroids" are a joke; there's no challenge to them, and it's not even a "stat check" because one of the earlier upgrades you get relating to bosses is one that makes all damage you do to bosses restore your fuel. All they really exist to do is force your run to stop there (killing a boss asteroid ends the run immediately).

• The node tree is of the "randomly-laid-out upgrades that you can't even see before unlocking the node before it" style with upgrades priced in such a way that (1) removes a lot of potential for planning out your build other than the immediate "do I buy A first now and then B after next round, or B first?" and (2) it's functionally almost completely linear.

• The plinko system is very cute and the a nice kind of casino-flashy-lights thing to have, but you will almost immediately tune it out because (being plinko) you have absolutely no agency over the drops, there's no depth to it at all; you're flushing buckets of ore into the plinko machine, you can't even really cross your fingers that the ore will fall into "the good slot," because it's going to fall into every fucking slot.

• between the plinko and the lootbox animations, the game gives you a lot of time to contemplate how this is actually a clever way of extending playtime (and, if I'm feeling particularly incredulous: perhaps ensuring people play past the 2 hour steam refund window) as you sit there waiting for it to finish cashing in the currency you just earned.

• There's "power ups" you can unlock but most of them don't actually increase your survivability or income rate at all, and (at time I played, at launch) the miner drill upgrade is actually worse than useless and I regretted unlocking it. Slows progress to a crawl while it's active.

• The "ending" of the game has you buy the most expensive upgrade in the game. I think 450M? And after you buy it, it... does nothing, other than unlock the next upgrade... which has the exact same price and also does nothing... other than unlock the next upgrade, which also costs... yeah you basically have to buy the last upgrade I think 6-7 times? And then, as usual, incredibly anticlimactic just instant credits.

In conclusion: quick little mindless game that has just enough "fun" and flashing lights that it might encourage you to sit through the utterly disappointing development choices you observe and see it through to the abrupt ending. I started playing it after all, I thought to myself, so I might as well, and it's not like I'm living up to my potential either, (sitting here writing this nonsense on christmas eve eve) so really, who am I to talk?
