Hey thanks for playing the game! Glad you enjoyed it and happy to see a different take on a similar concept from you aswell.

Interestingly enough making the hole was far harder than getting the grass to work with it. The grass itself is a shader I bought in a Humble Bundle a while back called Brute Force - Grass Shader (link). That shader allows for specific particle effects to interact with the grass and remove spots (for foot prints for example). So I created a circular particle effect around the hole which moves with it and constantly removes the grass.
Now what was more challenging was the hole itself. I have two floors. One floor with a hole, which is just a mesh, since i cant add a mesh collider to it and have it interact with rigidbodys, and making it a convex would break the hole. So i then added a bunch of box colliders around the hole to basically make the hitbox of the floor but leave the hole open. When you press w, a, s, d you move that entire floor with the hole. Since that would also move the golfballs and the grass, I made a second floor sliightly above it which is one big plane. The hole has a capsule collider trigger, and if a ball touches it, the layer of the ball changes which leads to it ignoring the solid floor above and dropping down, then interacting with the floor below which has the hole. If you move away quickly again, the layer switches back and the golf ball goes onto the floor above again.

I hope this explains it! It was a tricky situation with a rather straight forward but weird solution :P

PS: I was originally considering the name "flog" as it is golf backwards but also only one line away from the word flag. But it seemed a bit farfetched and everyone loves a bad good pun! :D

Heyo, thanks for the feedback! A very good point, I added the controls to the gamepage now!

Thank you! I highly appreciate your feedback! I agree, there were some really interesting and unplanned interactions that emerged while playing around with the physics and gameplay.

Thank you very much for the kind words! Made my day!

Thanks!

Unless UI elements are cut off, I believe the error is simply on my part, not really establishing and communicating how much you should see, as the game is simply meant to be rather zoomed in, with golf balls randomly flying into the small viewport.

But I would appreciate if you could send me a screenshot of what you see so I could assess if it is a bug.

Thank you! Yeah, I think the grass adds a lot, as it felt very bland without it, and such a simple game concept really needs every bit of 'juice' it can get.
