As a renoun wizard you lay claim to a new land and build your castle! But beware, for demon invaders roam the wilds. Grow your castle during the day then fight off waves of enemies at night!

Castillon is a bite sized strategy game about building and defending your growing castle realm.

We're big fans of the MOBA and base defense genre, and inspired by the shorter take of games like Thronefall and Bad North. So we're continuing down the simplified path, adding spells, traps and night time interactives, whilst changing up the modifers and enemy types.

Detailed Gameplay
During the day build your economy and defense as you see fit. Buildings can be placed anywhere whilst you and your villagers collect resources needed.

Utilize the schools of magic: Holy, Arcane, Necrotic and Engineering to defeat your foes.

Every morning the villagers get back to work and you can go exploring for treasure or help out with resource collection. Striking a balance between economy and defense is key!

Get your units into position, plan out your defenses before the next wave of battle begins!

At night enemies attack your defenses and try to destroy your castle. If they succeed your kingdom is lost. Build a an army, build defensive structures like towers and traps or improve your abilities and fight them off yourself!

After surviving all enemy waves, you unlock new weapons, spells and modifiers that allow you to customise your playstyle and load out.

There are 5 levels in Castillon that you unlock, each offering unique enemies, build options and fresh challenges.

Summary
Castillon is super compact experience. The main campaign is likely to take you 4-6 hours.
You can always adjust the difficulty with modifiers, all whilst chasing clever achievements.

The game has all the hallmarks of a tiny classic RTS base defense. It is crafted to provide the same fun but distilled in a bite sized and approachable way.
