I've not has so much fun playing a crazy golf game since buying 3D Ultra™ Minigolf Adventures well over 4 years ago. Vertiginous Golf, is not only beautiflul to look at , it's deviously more difficult to score compared to the older mini golf game. With local coop available now; and, as development progresses with up to 4 player multiplayer this is going to be a great game to play with your online mates. I can imagine the laugh your all going to have playing this.
The game is in early access; if you were lucky enought to buy it via the humble store a few days ago, you'd have got it for half price, right up to its release.
The game is a physics based first person exploratory mini golf game set in a steampunk universe. There are loads of innovations included such as first person mechanical humming bird that can be utilized to plan your shots, there' s a rewind facility that allows you to undo or rewind a shot without losing a stroke (basically a cheat system). The ball can also be controlled using the WASD keys, so rewinding part way, you can then adjust your shot accordingly. There's a whole host of other things included such as moving obstacles, mini helicopters, blockers, platforms, spinners, travelators and other interesting items (eg a glowing semi transparent trail showing you your previous shots) that help or hinder your progress. At the moment there are 18 holes with a further 27 + holes planned in future updates.

Highly recommended even at it's full price of £11.99 ($14.99). That's over £3 cheaper if you can find a friend in the US to gift it too you. ;)
