Good to know, I feel like the mining system is broken.

It takes forever to reach a level where it makes a significant difference, you can hardly notice anything. Based on the way it works your rate improves more for leveling at high levels than low, it should be the opposite.

Low levels should get better rewards for leveling, and have it gradually decrease as you level.

like it takes 10 secs to mine at 1, 9 at 2, 8.2 at 3, 7.5 at 4, 7 at 5, 6.6 at 6.

See what I mean? Eventually when you are at like 40 it would only be a slight difference, so that people don't get to insane levels and make too much money like on pc era, but leveling still helps.

Also the money gain needs to be buffed, even at like level 60(which no one has reached, highest I've heard of is someone at 32 that mines like all day) shoveling is still significantly faster.

Don't remove levels though, because people who put a lot of time into leveling like the level 32 would be really upset. if you do though, give us a large compensation, like say an additional $10 per rock mined.
