Powerup 1 is shown as a gem that lasts for 25 seconds. When the player touches it, the gem disappears, and the player gets an effect that lasts for 7 seconds. During these 7 seconds, when the player touches an enemy, the enemy gets launched away from the player. The enemy can also touch other enemies because of the effect, causing the other enemy to bounce off the island. This effect is shown by a ring around the player.
Powerup 2 is shown as an x that lasts for 5 seconds. When the player touches it, the x disappears, and the player gets an effect that lasts for 5 seconds. This effect causes the player to be invisible to all enemies.
