Played it again and that fixes it. Great balloon physics, reminds me of bad piggies in some way. There's quite a bit of potential to this idea, but it was tedious to earn RP and its a little weird that you can't invest in a hot air balloon right away. Would be great if there was some way to steer the balloon to avoid the birds making it more of a game requiring some skill, but now its more of random chance whether you get hit by a bird and plummet to the ground.
