I have several games by this developer and like them all. There are no ads or IAP, they use no battery, and don’t take much storage. Even though sounds can’t really be disabled, my volume is low so they don’t bother me. I actually prefer this developer’s older games to the newer ones, because the older ones don’t have the gap-bringer or ice-bringer type of obstacles that I found annoying (some may like those though). Anyway, this is a fun game to play during the holidays. Thank you developer!
