Corrupted Temple

This game was made in under 48h for the 11th Alakajam (page of the game) on the theme "Ancient Ruins".

The ruins of the ancient mushroom temple have been corrupted by some dark magic.

Your goal is to purify the ruins by shooting magical orbs at the stones that attack you. You also have the ability to dash in order to dodge their attacks.
Shooting orbs and dashing consumes your mana, which refills itself.
After purifying some stones you may receive a mana upgrade that allows you to store 1 more mana point and makes it refill faster.

Controls
Use the arrow keys to move
Press C to dash
Press X to shoot a magical orb (choose the direction with the arrow keys)
Press R to restart

(I have tested the game in Chrome and Safari, and the sound effects do not play in Safari, so play the game in Chrome if you can)
