Use the arrow keys or WASD to move. Press Z or J to shoot energy orbs at the boss. Press X or K to use a bomb that clears out the bosses attacks. Avoid the boss's attacks. There is a 1 second cool down between shots and you one have 3 bombs.
This is testing out the engine for a much better game I an going to make. The bosses will have the same-ish mechanics in that game. THIS IS NOT RELATED TO UNDERTALE. Or Pokemon for that matter. I just used Mewtwo as a placeholder because I was too lazy to make a boss sprite.
