Thank you for the amazing feedback! We are stoked that you liked the game! We are very happy how the breeding works and look forward to making even more monsters to defend your ores!
We are currently working on an update that will introduced a revamped tutorial, fix some UI, add music and sfx toggler! We cant upload at this current moment due to the game being part of a jam :o
Love the ideas that you provided, I can relay them to the main programmer and they may be able to change things up!
In terms of difficulty, we are exploring some ideas such as more miners, updating their stats, balancing monsters and fixing economy. These will take some time since they are very closely linked. Lots of testing will be required!
