Guarda Castelos Upgrade

Guarda Castelos Upgrade is a remake of Guarda Castelos. It's a simple fantasy shoot 'em up where you have to defend a castle wall against attacking orcs. Enemies move down at a straight line, attacking in their path. The orcs cannot harm you, but they will gradually break down the wall. If any enemy passes through a broken part of the wall and reaches the bottom of the screen it's game over. Over time tougher enemies will appear, going through armored orcs which take two hits, quick mages who attack from range, orcs carrying bombs and finally red mages who attack with a spread shot that can quickly damage large large parts of the castle wall.

Your ammo is limited, but refills periodically spawn at the edges of the screen that you have to hurry to pick up. Magic orbs also spawn, which will charge your next few shots with magic making them not only kill any enemy instantly but also go through any enemies in their path.

There are two game modes: "Normal" has a finite number of enemies and can be cleared, while "Nightmare" is endless. After clearing the normal mode or losing the game will record your high score.
