What it is

The first battle of the game: Isaac in the forest against two waves of Misty Mushes. The rules, the stats, the enemies’ AI and the rune recognizer come from the cartridge, with the data this site publishes.

The controls are those of a real-time strategy game: drag a box to select, right-click to move, the camera follows the edges of the screen and there is a minimap. To chant, hold L (Space) and draw the rune; when you let go, an arrow aims Fireball.

It is a version in development: the tutorial and the sounds are still missing.
