The depths idle

This game would be much better with tool-tips for everything, resources, stats, talents, etc.

Some things to comment and explain in this game: 1. Returning with resources resets all miners and restores the drill to the setting defined bu upgrades. Don't rush with returns. 2. Upgrading components of the drill is essential. Leveling up the drill gives a drill that is stronger than the one one level lower with capped upgrades. 3. You don't trade coal and other resources to gold. You purchase gold generators with them, providing cyclic gold income. 4. On the left panel, the % indicator buffs all exp income (blueish-badge resource), an integer below defines the depth level of the mine and the green sliding square (right to depth indicator) shows how far are you througth current depth level. 5. Drilling time doubles each time you drill. You drill by 10x the amount of speed (green arrow indicator). Drill deeper as often as possible as this buffs your exp income. Don't destroy your drill. 6. This game is rather slow and unlocking stuff requires some time.

Rule number one on game makin: Don't saturate the player before starting playing with a 4 to 8 pages long tutorial, give them the basics, then explain the rest when it is actually necessary. Most players tend to skip them, ignore them, or even worst, actually try to understand them, and they end up really confused.

Speed bug was actually better than the normal crawl-like speed. Most incremental games have speed upgrades, prevents the mind numbing boredom setting in in mid game or later, especially since resources depend on depth, which quickly is a matter of waiting for hours for drill recharge
