1) Ads usually pop up before or after game play, which are tolerable, HOWEVER Escalators did not do this. Their free version has ads while you’re playing resulting in loss of points & is very frustrating. It’s marketing is towards driving you to buy the game without ads.
2) Aside from that, the game has multiple game play errors (clearly wasn’t tested enough). Particularly in the moving escalator round, you typically are forced to re-start the round & is just annoying bugs like these weren’t fixed when the escalators don’t show up to allow you to move or a person is flowing on the side & can no longer move.
3) Along with this, I’ve found I can’t play competitively without my phone completely crashing out of the app due to the amount of data needed to be computed when too many players are accumulating (potentially damaging hardware long term). This is a particular drawback when playing in the Fight round, where it is again, lightly to crash out of the app. My phone (iPhone SE) isn’t the problem. The programmer should know the limitations of their main consumer’s device, as opposed to their processor on their PC development tools.
I like the game, due to its premise. But it is ridiculously easy & wish it was slightly harder to play. (Ex: Endless Version where you are more likely to die, timed variant get to the end quicker for more bonus points, highest score on single round competing against yourself)
