Idle Deepcore

I will never stop hating on prestige.
The worst mechanic to ever be used in gaming, and for some reason people keep on lazily copying it.
Yep, go redo everything again to advance a bit more.. just faster.

Other than that, it's a basic mining "automation" idler. The options are boring, the upgrades and skills are slow and unoriginal.
I think the only positive in this game is having the meta map and simultaneous mining areas - and they still haven't really squeezed the potential out of both of these concepts.

Progression feels too fast and because of that, it expedites itself into mediocrity. A prestige system should not allow you to have twenty times the amount of a resource that you need to enact the next prestige only to gate you behind a normal gameplay model that doesn't feel much improved than it's pre-prestige state. Because it's too easy to prestige the first time, the subsequent ones feel even less relevant and you find yourself cycling through prestige restarts with absolutely no sense of fulfilment as the player.

The individual map tiles were quite inconsequential regarding the type of mineral deposit bonuses they had. Instead it became a rush to just move outward toward any direction to simply gain generic improvements. There's so much room for improvement on the map such as events, encounters (of some type), or anything other than the boring "select a spot, mine a spot" mechanic it currently presents.

A couple of the mining equipment varieties are objectively worse than the starting jackhammers. That needs adjustment because their cost isn't commensurate with their output. The late stage equipment moves so fast visually that it's painful to look at the screen. There's just something missing regarding a satisfactory visual style.

Dev needs to change the UI size so that all mineral types fit on the screen without the need to scroll. Overall, the mineral types are fun for the first few smelting opportunities because it's methodical and paced logically. The later stage ores and smelted materials just become irrelevant because they are attained so swiftly and progressed through so rapidly. They feel inconsequential other than a numerical variable geared towards simply opening up more boring map tiles.

Something's wrong with the pacing and the prestige loop. Maybe some of what I've mentioned above can help pinpoint what those things are, but it seems like it could be really fun if some parts slow down, others speed up, and prestige is reworked to make it feel impactful.

Progression is very slow and can be heavily impeded by not buying/expanding to the proper land (which isn't ever explicitly explained), but even once you have opened all the necessary mines to get the full spread of the resources, progress is still very slow and eventually gets to a monotonous crawl where you're slowly buying upgrades and land while occasionally unlocking a skill. Didn't get to the full end game since it was just more of all the same, but can't really recommend it with the bland progression there is now.
