Choose by comfort and visibility
On a phone, place your hand so your tapping finger does not cover the companion or the next gap. The useful question is whether you can see the approach while tapping, rather than whether a particular finger is theoretically faster. Settle into a grip before you start a run.
On a computer, either clicking the game or pressing Space can keep your attention on the forest. Try a few attempts with one method before switching. Changing input and window shape together makes it hard to identify which change helped.
Give keyboard input the right destination
Focus matters on a desktop. A menu button, link, or text field can receive keyboard input instead of the play area. Close the game menu or share dialog, then place focus back in the game before assessing whether Space works.
ORBIT ignores repeated keydown events from holding a key. Treat Space as a deliberate press for each input. A held key is not an automatic tapping mode, and changing how long you hold it is not a substitute for deciding when to press.
Compare setups without losing the context
Use the same companion and course for a useful comparison, and keep a similar game-window shape. A wider view changes how much of the forest you can see, so a new personal best after moving to desktop does not isolate the effect of keyboard control.
Progress is local to the browser context. If you test on another device or browser, a different best or missing discovery can reflect separate storage. You can compare your experience without expecting the game to merge those attempts into one shared profile.
