Count decisions as well as buttons
A game can use one button while asking for precise, frequent decisions. The itch.io one-button category describes a single-button control method and includes multiple genres, rather than one fixed pace of play. When choosing a game, ask what happens between inputs. Does the character keep moving toward danger, does a turn wait for you, or do resources accumulate independently? The button count alone cannot tell you.
Understand ORBIT’s active loop
In ORBIT, the companion travels along a curve and the camera continues forward. Each reversal changes the future path. A run can end by touching a branch, leaving the vertical clearing or falling behind the camera. Discoveries accumulate from gaps you actually clear; there is no offline resource-production system to manage. The animated ready-screen demonstration shows motion, but it does not earn scores or discoveries for you.
Choose according to your available attention
If you want to watch numbers grow while rarely interacting, ORBIT’s active run is a poor match for that expectation. If you want a small set of controls with decisions that matter immediately, it may fit. Try a few attempts and judge whether reading the path is enjoyable. A useful selection checklist is input complexity, decision frequency, consequences of waiting and persistence between visits. Evaluating those separately avoids confusing a simple interface with a game that can safely play itself while you focus elsewhere.
