Wow! I’m glad you made it! Good job!
Definitely I’ll tune some elements of the levels when the jam finish, such as the rotating stars that you mentioned.
About the longer levels on fullscreen mode, I couldn’t reproduce it but I will take into consideration for further updates. At the moment the way the floating objects are spawned relay on time, not on distance. It means that an object/block of objects are spawned after some time (seconds or ms) and not in a specific km. If you pick up a boost item for example, the character goes faster but the spawning keep the same pace. I ran out of time to improve the level design and some of them might be really small, so if you go fast you might see the level repeating since each level will loop until you reach the next one.
Thanks so much for your review and for playing! I really appreciate it.
