+# Motivations
+
+I just like this FFX game design idea and I want to test some python tools I haven’t used in projects yet such as ruff and pytest.
+
+No clear roadmap, just 2D graphics fun

 # Roadmap ideas
 
 - [ ] seeded RNG
-- [ ] pattern: circle, line
+- [ ] pattern: classic circles, line to connect far away patterns
+- [ ] path finding
