This first checkpoint was TOUGH. Especially since the game is Coin Waster style until this point. There was only a few easy segments that made you redo them, but prior to this it was basically pay to win, start right where you died.
After this first checkpoint it went much smoother. I saved atleast 2 bombs for the mech boss with the saw. You have to beat the fire mid boss and the mech boss to get to the next checkpoint. The mech boss is predictable enough but takes long, the enemies are dense prior though.
Deaths are edited out for this video only, the other is raw since it is mostly pumping digital coins.
