Nice game. Finished it in about 1 hour and a half, all max tier tools and all bots with highest tier hammer (because is the best tool for them).
If you plan to work on the game, some suggestions:
- Instead of clicking each time to trade a gem to a higher tier gem in the machine, make it to tread all with just a click. I had over 30k brown, black and red gems to trade, but I was afraid to develop RSI for clicking too much.
- Make the bot's AI somewhat configurable, like "mine the lowest value gem, mine the highest value gem, "mine the closest gem", "if 'specific color gem' exists, mine it, else, mine closest". That sort of thing.
- Kinda unbalanced with the numbers. It was easier to buy the white bot than the light pink bot.
