Enemies
Enemies appear randomly throughout each level and may actively attack or passively damage the player. Killing multiple enemies between landing on the ground will result in combos and can yield bonuses. Most enemies can be stomped on which will kill them and recharge the player's gunboots. However, some enemies will damage the player if stomped on; these enemies generally display the secondary color (default red) along their top side as a reminder that they should not be stepped on.
