Glad you enjoyed the game, and I hope your stomach gets better soon :)
Regarding the feedback:
- Bonus levels are an ongoing struggle for ours in terms of presenting them to the player without also making them stray from the critical path. We have a new way of showing this in our upcoming game and we hope it'll work out better than what we did in Golf Peaks.
- This effect of rising from the mist was actually our initial idea, but we ran into some technical issues with doing that due to how our shaders are set up, so we opted for the simpler camera effect you can see in the game today.
- We actually had a "golf club" visual for the cards in the earlier version of the game (see attached image) but we opted out against them because the image took up too much space and took away the player's focus from what the card will actually do :)
