+# Design Notes
+
+General design notes for radius-game.
+
+
+## Overview
+
+Pitch: Gradius x noita wands (other games have similar mechanics but thats the only one I know by name).
+
+
+## Weapons
+- base weapon is simple
+- can add effects to the weapon to modify its behavior
+    - set number of slots i.e. 10? 20?
+    - effects inlcude:
+        - multiplier: increases number of firing nodes
+        - speed: increases speed of projectile
+        - rate: increases rate of fire
+        - size: makes projectile larger
+        - explosive?: projectile explodes after a certain time
+        - sequential?: projectile spawns more projectiles after a certain time
+        - status effects?: projectiles apply different damage types
+
+
+## Spawners
+
+- set spawner node locations
+- each node can be used as a target for instancing an enemy spawner that spawns a particular enemy
+    - for a configured amount of time / configured rate
+- define in a cfg file for easier customising of enemies
+
+
+## Levels
+
+- levels are just a sequence of enemies spawned at given nodes after certain delays
+- each level ends with a big boss
+- define in a cfg file to allow easier writing / tweaking of levels
