I use keyboard more, but I think it matter less when user invoke the upgrade during less dangerous time.
Good point. :) I'll ponder on this. There's a slight chance it makes the game a bit too easy, as you could then wait with your level ups to get that emergency repair. Then again it makes the game harder as well, as you're hoarding levels and missing out on upgrades in the meanwhile. This could even it out in the end. But I hear you! Thank you for excellent feedback.
Anyways. I'm trying to refrain from patching this weekend, as I got the telemetry working just yesterday and now I gather some data on the runs. Already I found and fixed some issues. For example I noticed that there were surprising amount of people leaving in under 10 seconds into the game. Figured it was because the game screen didn't focus back when you clicked the Itch iframe to fullscreen - and people couldn't move anymore. Now the game forces you to click back and activate the window, or choose full screen mode inside the game. Under 10 second games dropped significantly.
So I hope the next patches will be meaningful ones. :) Now I try to just watch for couple of days and not tinker at all. ;)
