I like how in this world you can buy as much iron as you want for free and then sell it at eight units for 30 bucks. Either the guys that mine the iron are super rich and don't need the cash or the economy is very, very biased towards you...
An idea for a future installment:
Mining Idle:
Send machines down underground, sell the minerals, gather money, buy upgrades like harder drills, thermal resistance, cave-in defense, etc.
@p90pwns Anna is totally awesome and great for bosses, especially with the Razor Leaf subweapon. Just unload it on the boss, dodge and shoot the main weapon (you don't have to be underneath the target, which is awesome) then when it's charged, unload again. Rinse and repeat for every wave (it's much easier than with other subweapons)
Of course, I can't speak for everyone. I just find this good for bosses myself but you might have other tactics.
For anyone who wants a high score on Pacifist Mode:
Buy all three weapon damage reduction and "no counter-bomb" handicaps, as well as pacifist mode. Equipping all of these will increase your score without hindering your pacifist mode performance-it doesn't matter how little damage your weapons do if you can't fire them!
This also raises your multiplier enough to equip all three bullet speed cheats without going under three stars, so you can have an easier experience!
+ this up if you want!
Note: Best to give Matt Terra Drill and Nat Dispel. that way you can hit buffed foes hard before dispelling them. + for more tips and to keep this alive!!
If you're trying to get the very high damage medals (30k, 300k, 3m etc)
try finding a very high level enemy and casting an instant death spell on it...
