Gameplay Overview

The player has a standard shot and a sub-shot, as well bombs that do no damage but give a fair amount of i-frames. The sub-shot also has some sort of short ranged aura. Main shot uses a coin magnet, while sub-shot uses a medal magnet.


Scoring consists of chaining coins and medals. Coins is what increases the value of the medals. Medals are created by using the sub-shot to shoot at coins to convert them. Medal value can reach up to level 10.

The chaining is increased by constantly collecting coins and medals, and if collecting performance is done properly, chain can reach MAX value.
