Stacked Arrows
Hold anywhere on the screen to climb and release to fall. A quick tap slows your dive. Each arrow blasts a hole where it ends, and the next arrow flies through it.
Each day's cave can be cleared once, so every result on the leaderboard is a fair first run. A new cave opens at 00:00 UTC. Free mode lets you practise any cave as often as you like.
The app checks the current date with trusted public servers so everyone gets the same cave on the same day and the date can't be changed from the phone's settings. Endless and Free work without a connection.
Make sure you are signed in to Game Center (Settings › Game Center). If your result was saved while the date couldn't be confirmed, it is sent automatically the next time the app is online.
