It would be more enjoyable if there was some sort of bonus granted for reaching a certain height and distance; as it stands now, there is no reason to try for either other than to go for the trophies. After that it's just trying to get the coins. On top of that, I see no benefit of getting the presents other than for the trophy either. Maybe if there were cosmetic add-ons (costumes etc) that presents unlocked?
I like this game a lot, you don't see too many decent point-and-clicks adventure games anymore. Though I did find the ending anticlimactic (why show that thing at the end if you never see it again?) I thought it was great.
Though is anyone else bothered by the fact that the ship had a steering wheel?
Great game but one complaint: You need to either have a manual reload, or you need to be able to switch weapons while reloading. That way you have to choose between reloading(slower) or switching to another weapon.
