It may have been better to hard-code the camera's y position, just following the camera on the x (sort of like the first super mario bros), but great presentation. You have no idea how much a cute  aesthetic and some nice royalty free music adds to the experience.

Oh, and you probably know this, but the collision mechanics are a little sticky when you run into a wall. That's a hard thing to fix though, so I wouldn't hold it against you.

I made it to the end!

I'm a sucker for silly plots, and the super brief cutscene at the start got a chortle out of me. The themes of the different levels were a great setting, with the unexpected Bible one taking the cake!

Now, I don't think I need to go in detail about the shortcomings of the game. It looks to me that you were experimenting with some features still, so, for the purposes of the jam, I think that you did alright with Telebuster. I'd only mention that, on future platformers that depend on jumping onto lower levels, consider moving the camera down and somewhat. Level 2 was challenging due to so the leaps of faith. Level 3, in comparison, was a breeze, and it did feel tight and even fun as it had some verticality to it.

Good job nevertheless! 👍
