Nearly great game
It’s nearly a great game, I played it for a couple of days, but then I hit an irreversible problem of buying “Skip level to…” which turns out is actually forcing me to lower performance, as I can’t start from lvl 1, which I realised is the best level to start at to generate the most money with the mines. So even when starting at level 9 I already went from maxing at lvl 110 to about 70… I’d call it a bug and I’d allow player to choose lvl 1 or somehow allow developing the mines and then skip the levels. Additional idea - stats for all the turrets, towers and allies, so the player can see which ones are the most effective
