I'm going to try and make my own Touhou mod!
The Bubbler is replaced by the Heisoku, which has been buffed to deal high damage. Firing orb projectiles.
The Machine Gun is replaced by the Paper Tags, rapidly fires low damage ofuda's.
The Snake is Replaced by the Master Spark, firing high damage lasers the spur shoots.
I have a general idea for the story but I haven't came up with anything yet, and the name is still being decided.
I'll likely change the UI a bit but for now it works.
In this image you can see the first area of the mod. Always subject to change!
You should be set on the Event Flag I assume (FL+XXXX for any flag between 1 and 7999 assigned to the Life Capsule) or (DNPXXXX, XXXX being the event number being given to the Life Capsule, it's pretty useful to use instead of just <FL+ if you know what you're doing), so for NPC Flags, you'll need to select the life capsule through the Entity Map Editor and give it the NPC Flag "No Appear if flagID set" (0x4000 if you're using Cave Editor), like in the image.
