Geraldinho — About this game
Geraldinho is thrown into a video game full of monsters, dice and unstable platforms. Shooting shrinks an enemy, but you still need to touch it before it turns into an eyeball that attacks the timer. Dice release more creatures, while blocks can obstruct both you and your enemies. Some platforms vanish if you linger, so plan a route that lets you collect small enemies without becoming trapped. Adjusting your fall speed helps you reach the next ledge and keep the stage moving.
