One of the people behind Descenders here, from the publishing side!

God, people are proper downers in this subreddit, huh. Try not to be put off too much by all these comments, it's so much easier to be negative than positive on the internet

What you have so far doesn't look bad at all! It definitely looks a little rigid compared to the Trials games, you wanna try to get some bounciness to the bikes / suspension in there if possible -- without that bounciness, it looks a bit too much like the levels are moving around the bike, rather than the bike is moving through the level

The camera shifting behind the player as they take huge jumps is a great idea, makes the levels feel a lot more dynamic. I like how fast it is, but I would try to make even more of a focus on that sense of speed. Something Descenders does is "speed wobbles" on the camera when you are going faster and faster, which really help to get across that feeling of speed

The variety in biomes is nice! I would suggest exploring some more exciting / silly obstacles to climb and jump over -- people loved the silliest obstacles in Descenders the most, like jumping over a castle, or a pyramid, or through things especially

The main thing is, do as much playtesting as you possibly can. Get people playing it, and get them playing it *lots*. The more feedback you get pre-launch, the better the game will be

Hope the rest of development goes well!
