Oh man, the duality of needing to pew-pew into the sky, but the ground keeps hurting me randomly based on patterns I do not see because I am looking up? Brutal.
I think you have definitely got an interesting idea here, I just wish it started off a little easier, and clearer in game that the timer relates to the ground. From the start you are essentially looking up, so it is a weird shift.
I did have fun though, shifting between run & gun to jump & gun…
Good job, really interesting idea!
