So, so hard.. I wish it had checkpoints. Not even after every delivery, but, like, 2 or 3 for the entire game would be great. I eventually had to give up after playing for 15 minutes. I had just delivered the hay and was grabbing the meteor when the hay came barreling down from above and smooshed me. Hilarious, but it wasn't as hilarious because I had to go get the boulder to the first checkpoint for the 20th time, oof.
Or, even if you're super against checkpoints, maybe it would be cool if you could use a fuel station more than once? Like, I would have a wonky takeoff from a fuel station and know I wouldn't be able to make it to the next checkpoint. Rather than starting over, what if I could just pop back to the fuel station with my remaining fuel and start again from 1100 fuel there?
I also kind of wish the hook went outwards from your butt rather than straight down. It was pretty tricky getting the right angle a lot of the time. If I could snatch a package in motion from a 45 degree angle that would be coolio.
