oh yeah almost forgot:
6. the chests.it's nice that you can buy an upgrade for it to auto smash the chest. but the very popup itself gets annoying too, as you are y´jsut in the right flow of mining blocks and have tointerrupt each time to basically click away a popup.jsut give an upgrade that auto accepts those too or doesnt show them anymore and jsut gives a "+3 to mining damage" hint in the corner or such.
sad that zeppelinsdont exist in the actual play mode. they looking good.
