About this game
Donjon Defense is a game in the genre of tower defense. In this case, defense of the castle, consisting of... only one tower. Build walls, hire different warriors, resist attacks. Build a real fortress, hardened in countless assaults.
Two game modes
Expansion – this game mode is similar to a sandbox. Here you can endlessly build and improve your castle, fighting off attacks provoked by the expansion of your castle. In this mode, you will receive the bulk of the reward from the protected villages, as well as from victories in the Siege mode.
Siege – this mode is more like a classic defense. You have to withstand 10 waves of attack, each of which begins in its time. In this mode, you receive rewards only for destroying mobs. If you win, all the gold you will not spend will be transferred to your treasury in Expansion mode.
Five types of units that will help protect your Donjon and six types of hostile mobs. All of them have their strengths and weaknesses, which makes them excellent in one situation and helpless in the other.
Building
You can build a castle from parts of walls, merlons and roofs, by a character that can only move on the castle walls.

Update to version 0.0.3
This update was focused mainly on the Expansion mode. I hope this will make the game in this mode more fun and relaxed, like a sandbox, in comparison with the Siege mode. Changed the balance of arquebusers (damage reduced by 10, armor increased by 1). Some descriptions have been changed. Fixed bug with incorrect protection for units with iron merlons. Small changes in particles. Expansion mode changed: The villages have been replaced by various productional buildings (now there are 7 of them). Added inventory for units. Now in the Expansion mode, units can be equipped with weapons and armor of their own production, which increases their effectiveness. Added resources. Now there are 13, they can be sold, or produced some from others (more valuable ones). Some can be transferred to units. Also, the Expansion mode, there was a rebalance. Enemies now only appear after the construction of productional buildings. The cost of wooden walls is reduced. Most importantly, the color of the grass is changed :)Read full article on Community Announcements (Obi-Wanya)Patch NotesOfficial

Update to version 0.0.2
Hello everyone! Were questions about unusual gameplay. There were a some incomprehensible things, in this update I tried to fix it and make the management more familiar. I also tried to make more detailed hints in the Expansion mode. Fixed a crash associated with hiring a unit after the destruction of the donjon. Now the menu can be closed with the Esc key. Has been added the icon that turns on / off the fields of view. Changed the construction system. Removed the character-builder, now the construction is carried out with the mouse. Slightly changed the font and description. Added a frame around the selected units. The tool for removing previously built walls is added. The training has been remade. I hope this will make the game more fun for you.Read full article on Community Announcements (Obi-Wanya)Patch NotesOfficial
