Thanks for checking out the game :D
A tutorial / tool tips is something we have been talking about wanting to add to smooth out the gameplay experience once the jam voting is over and we can make non game breaking bug fixes. We ended up pivoting our idea about half way through the jam after we realized our original idea wasn't gonna play how we wanted it to. So unfortunately it was something we had to cut due to the jam deadline fast approaching (as they always do lol) to get core gameplay finished and then hopefully really polish it up later.
combo was our fun way of giving players who wanted to actively mine more of an incentive and reward for engaging with the "clicker" aspect, but it is still beatable if u just wanna idle away and have your robot minions do all the work for you! Thanks for the feedback, glad you were able to figured things out.
