you should be able to stand up in air after a small amount of time because when you're fighting 10 hydras, going up through them and back down can almost end a hole life.
just a few ideas: on the story mode have each of the areas have a special bird that you can only get during that period, like a dodo bird in a prehistoric area, and maybe explain what up with the rips in time and space. also a little less invincibility in endless mode i let it go without doing a thing and made it half an hour.
You're absolutely right. I need to go back and fix that. Thx for the heads up.
