The combat system is turn-based and very similar to other games like Final Fantasy Tactics and Disgaea. Each character has its own abilities, strengths, and weaknesses.
The warrior, for example, can block attacks to minimize damage. The wizard, on the other hand, can teleport from one place to another and cast harmful spells from a distance.
The game has a fairly simple story with a very short plot, but it makes up for this with detailed graphics that show off the modeling and drawing of each character.
Dungeon Door is a fun role-playing and strategy game that fans of SRPG will especially enjoy, given that there aren't too many options like this for PCs.
