Look out for those chasms!
In this procedurally generated endless runner, you play as Alto who is either snowboarding down the slopes to catch some llamas or sand boarding across a vast desert. While hopping over rocks is easy, making massive leaps over huge gaps requires more speed, and speed is only gained through doing tricks: mainly back flipping. Don't land on your head!
The slope goes forever!
It's a very pretty game and super easy control wise. While you can buy upgrades if you collect enough coins, I'm more impressed with the achievement based leveling system which I think more games should do. For example, to reach level two requires traveling x distance, jumping over 3 rocks and catching 5 llamas or something and each subsequent level has more demanding requirements.
It's quite a fun game and is somewhat soothing but like all endless runners gets repetitive very quickly. I give it two llamas out of five.
Insight: Don't look at Alto. Look at the right edge of the screen to be able to react in time.
