Well done on the mood an simplicity of the game. Each of the 3 obstacles has a slightly different challenged connected to a clear theme to know what each does. I was able to beat level 3 before the obstacles became too fast for me to dodge.
The retro graphics fit well too. Given more time I think reducing the screen-shake per landing hop, or an option for turning it off, would be good. Speaking of camera movement, the camera swooping down for a level preview is a nice detail for communicating to players.
The music is upbeat and catchy too. Adding audio for vehicles rushing by might be good, but I could see how it could easily overwhelm or confuse players if not treated carefully so keeping them silent for the game jam feels like the right call. Thank you for listing your tools, it sounds like you have a good grasp on how to use them.
In my next game I will definitely use more feedback, since I discovered that most players never finish the game (which is sad beacuse i hid an easter egg for those who finish it) and that the game is too hard. I will also add accessability options to my next games since I'm noticing that people's preferences are so diverse!! You dislike much screenshake, while my friends thinks it adds to the juice. I'm glad that you liked the music! I'm really proud of it.
Your feedback is so good, you really understand the details that often goes unadressed. Thank you for playing and giving this awesome feedback!
