✦ AI summary

oO is a simple circle-dodging game that players praise for its interesting core concept and accessibility at a low price point, but the difficulty curve becomes punishing beyond the early levels with frame-perfect requirements and frustrating bugs that undermine precision-based gameplay. While some find satisfaction in overcoming its hard achievements, many report that later levels and the endless mode challenge feel more dependent on luck than skill, leading to burnout rather than enjoyment.

[h2] Review:[/h2] oOooOoOOOoOOOo [h2] Completionist Review:[/h2] Reaching a score of 100 in Endless Mode—after countless failures in the 90s—gave me a dopamine rush like no other. Games with hard achievements like this remind me of the euphoria that comes from overcoming what once seemed insurmountable.

This is my 13th reason. If ever I'm found dead alone in my apartment, this game will be to blame.

a nice, simple game where you just flip from circle to circle dodging spikes. a good relaxing game for ~1$... ... until you decide you want every achievement and see theres an achievement for getting to 100 in endless mode and then you realize how its going to be and you spend hours being @.@ until you eventually get it! ᗡ:

Level 1 and 2 are humane. Level 3 has parts that require frame-perfect execution. Or in other words: It takes luck to beat it. In the end I made it, but my motivation to go on and beat the last level is gone.

very fun and underrated but very hard
Not recommended Jun 20, 2026
The concept is interesting but after the second chapter the game becomes insanely annoying and time-consuming, plus that endless challenge nearly made me go insane. Plus the amount of buggy moments were too much, like when even the click was accurate you do not switch circles but only shift your position (especially with the smallest circles).

Games like Dying Light are easy to find if you only want parkour or only want zombies. These eight keep the part that matters: a city that becomes a different place after dark.

Games like Portal 2 all share one habit: teach a single impossible trick, then spend a campaign breaking it. From rewinding objects through time to Escher geometry that loops back on itself.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
