I may be a few days late to the party, but I thought I'd throw in my input, anyway.
First off, I just want to say this game is fucking sick. Like, holy shit, it's so fun.
That said, it, obviously—as this is a primal version—needs and will be improved. I saw some people say that this is better than myTP. In certain ways, it definitely is. The character model is much smoother; the grabs, rotations, and other tricks are far more realistic looking and feeling; and there's no stupid point system.
However, from a purely technological—nerd—sense, myTP is a better game. Your game has the potential to be so much better than it, though!
–I'm not sure what it's like to play it on a controller, as I don't have one, but add sensitivity to the rotations. I find that I over-rotate a lot. If there is sensitivity on controllers, try to add some sort of that to keyboard players. A fundamental part of a truly good game is to ensure that there are no players that feel left out.
–I've seen this, and I'm sure you have as well, but find a way to make "pop" and "speed" be different buttons.
–It's really really really really really really really really really cool that you can set an edge on rails. I don't think I can emphasize that enough. But, I find my character setting an edge every single time I go on a rail. It seems like you're aiming for realism here—duh—so stick with it. Not every skier sets an edge that hard every time they hit a rail. Maybe implement an "edge-setting" button, or only have it take effect at a certain angle.
–I know that it's literally three days old (less, maybe?), but my biggest problem with it is that there's no repercussions for falling. I'm also aware of that fact that it's supposed to be a game of pure fun, and for that, I really don't think points should be added. There still should be something to make the player not want to fall. At the very least, have the character fall over, haha.
And, for the far future:
–Half- and quarter-pipes.
–Longer levels.
–Multiple levels.
–Aesthetic character customizations, ie: skis, outerwear.
–Afterbang button?
–Possibly level customization, as in Gnarshmallow style.
–Better level design: jump line... rail line... mix of both...
I know this is a lot of stuff, and I am well aware that this game is new and hard to make. These are merely suggestions. Again, though, I'm very impressed. Even in such a basic state, this is one of the most addictive games I've played in a really long time. It's everything the 3D Gnarshmallow/JibLife/EA Ski should've been! Keep up the good work!
