When initially run, it was a great time waster and was very calming and relaxed. But if you close it and reopen it... expect tons of loud and unskippable ads, a ridiculous difficulty spike, glitched/invisible obstacles (trees are suddenly considered rocks..??), etc. My suggestion to the creators: have ads for revives/continues, and have the ads play at the game's volume, not full blast and inflicting physical pain on your players.
