I bought the full version of the game and I am really enjoying it! Great gameplay with a nice balance of realism and arcade style mechanics. It's simple, relaxing, and fun.
I genuinely hope there will be updates in the future to add more features, like smoke under the player's feet, new maps, caves, secrets, and so on.
Maybe also consider improving the balance of how gold coins are earned, it feels a bit hard at the beginning without a powerful wingsuit.
Also, I feel like after unlocking certain skills, the wingsuit actually becomes a bit harder to control, especially with the skills on the left side of the skill tree. It feels like it slides too much horizontally, making it harder to maneuver precisely and losing a little bit the realism.
I've reached the third snow map and explored a lot already, really great work. Keep it up!
