Gravity controls the skull ghost. i learned the hard way that you must avoid cave walls and falling to survive. Each enemy can be hit directly or used to collide with other enemies in the dark cavern. Destroying stone obstacles is key to progress.
Clicking or tapping makes the skull fly through the cave. Aim to hit ten enemies to activate fire power, which lets you destroy any obstacle. Use enemies to break stone barriers, but watch out for walls. Navigate the dark cavern while avoiding crashes, which is the main challenge.
Often, you control a flying skull ghost inside an eerie cave. The main action is to click or tap to move and avoid obstacles. You can use enemies to break stone barriers, which is kinda weird anyway, but it works. Their goal is to hit ten enemies for fire power.
Simple tip: focus on using enemies to collide with each other. i discovered that hitting ten enemies gives you fire power to destroy stone obstacles. This mechanic is more effective then just flying blindly. Try to plan your path through the dark cavern to avoid cave walls and falling.
Stuff is simple here. You fly a skull ghost in a dark cave. Click or tap to move. Avoid cave walls and falling. Hit enemy skulls directly or make them crash into each other. Use enemies to break stone obstacles. Hit ten enemies to get fire power and destroy everything. That is the main thingy.
