June 13th 2021 - Update without playable build

- Waves and stages system, easier for me to fine tune how mobs will spawn, not just random mobs at random places.

- New UI. I hope I can solidify on this design since redesigning the UI takes so much time.

- Modules now have their own energy. Full energy module will build itself really fast.

- Destroyed tower will now return an empty energy module. Module's energy will be refill over time, but if reinstall said module immediately, it will not have enough energy to build itself.

• Next step:
  • Improve menu UI.
  • Upgrade system.
  • Make a playable next build.
