To elaborate on my previous comment.. The game doesn't seem finished. It's probably at around 50% completed by the developers. So many little things that bring the game right down in my eyes such as the 'End Now' bug to the lack of additional courses. Upgrades don't seem to have much affect in opening a gap between you and the AI and putting/actually getting the ball into the hole is just terrible. Shame to see such a poor game put online by a highly acclaimed developer.
A lot of levels can be completed without really having to do anything but let the monster drop to the ground. There were some really good levels but a lot of lazy ones as well. Liked the game but needs to be more challenging with new levels/characters.
