Looks like a nice game, however it is missing some description. To me it is not obvious at all how/why life is reduced as the player goes up etc. Some basic "how to play" description would be a great addition!
thank you for your feedback,that mechanic was added to create a time urgency or else game would go on forever,and it forces you to activate powerup with the 'S' key,which refills health but reduces jump height and speed so needs to be carefully planned. will add an initial tutorial Post game jam.
