Today I'm sharing a couple of essential features of my game:
The first is bullets flying everywhere!
In this room the objective is to touch the two flags to remove the gate on the right.
This is made difficult by the three enemies shooting bullets constantly. Here you could choose to engage them all, but it's probably smarter to evade and try to get to the flags as fast as possible.
Using bullets + parries to advance
In this room you first have to evade / battle a set of enemies, until you come up to the wall at the bottom. This wall can be broken with a parried enemy bullet. After which you encounter the final trap of the room.
