After trying 10 times for the consecutive perfect jumps, I realized how hard it was and exited cinematic mode to come see if the comments agreed. Of course, in the smaller game window, it was the very next run that I got the 5 in a row. Decent game, but nothing special. 4/5
Only get/upgrade collectors and coin limit when you need it. Have fun at first learning the game and getting initial money and go for top machine gunners with full dexterity and power. Shouldn't need more than 2 fully upgraded collectors in the end.
It'll be a ~15-30 min grind any way you do it. Obviously not an idle game, meant to be quick fun
Hard badge is a piece of cake once you have the minigun. Save up your money in the early going and buy Scavenger's. Get first SMG for the first boss at level 20. Get the minigun by level 40 and you're good to go.
