Hi, thanks for making this awesome game, I like the concept very much!
But...
I have some problem with FPS. I have Intel HD 5500 and on 1280x720 it runs only (I think) on 5-10 FPS. CS:GO runs on low details on 20-25 FPS. So you can maybe add to the game some detail quality and shader settings.
Also few tips that you can add..
Middle stations of gondolas. Player will be able to make middle station of gondala where can skiers go down or up and then the total lenght of gondala can be longer.
Restaurants and Hotels. Hotels sorted by quality’s (1-star, 2-star, ...)
Snow cannons. Snow will be somewhere melting due to temperature (need to add temperature mechanics) and player will have to place there snow cannons and connect it to snow storage.
High poly models. When the game will not be in alpha you can add high poly models. It just feels more realistic with it.
Money system. Running cost, building cost, staff wages, lift tickets, ...
