With very little going on mechanically Kolumno is a pretty basic game, with your only goal on each stage being to successfully get a ball to drop into a hole. While this is initially a pretty simple task, simply requiring you to dial into a sense of timing for when to release the ball so it isn’t knocked out, the further you get the more the challenge will increase. Adding new elements of control, like being able to briefly pause the ball as it drops, get introduced as you go attempting to keep the feel as fresh as possible. One complaint is that new abilities really aren’t explained so precisely how they work or what you’re supposed to do may take some trial and error. It’s a very basic game but not bad for a temporary distraction to break up your day.
