I didn't get far at all, so I ended up watching the video you posted below. The music is indeed very nice and so is the concept. I also like the sleek artstyle.
I'm usually pretty good at these 3D platformers (played a fair bit of Recore which is also made in Unity) but I wasn't able to get used to this one for two main reasons I think:
- The transparent platforms are super offputting: in a game like this where precision is needed, I like to see where exactly the current platform ends and where the next one begins.
- Why the "W" binding instead of Space, which is usually used for jumps in similar games? You could even bind both of them and let the player choose his favourite.
Aside from that, there is a difficulty problem as is often the case with jam games (it's so hard to make a game and balance its difficulty in so little time). Again, I want to refer to this Quill18 video on game jams. It was frustrating to stumble so much on the very first obstacles, without getting to hear the rest of the (great) music, and also having to click on "start" again each time instead of being spawned at the start / last checkpoint again. Here again, the different levels (or are they randomly generated?) are nice but also make it harder to learn the first steps.
I hope this helps, and I look forward to see you in the next jam! Take care!
