Ah right, I never though of porting it to Linux as well. Good point, will look into it!
Sorry for the performance issue, in webgl it is hard to play indeed, a the platforming is tough. Some food for thought for my next Jam for sure!
So, I finally booted it up on windows to play it. I think the divide between the physics controls sections and the platforming sections were a neat idea, it's like those games that dabble in different genres and gameplay sections. It's good to keep a good pacing, and I think you did a good job on the controls of both sections. If I would point out problems, I think the biggest one was not being able to see where the rocket is landing, each first time I felt like I was setup to die so I could know where to angle the rocket next time, there was very little room for reaction. But yeah, I can see a lot of care were put into the platforming controls, you had dash, wall jump, moving platforms and even the janky physics platforms. Good job!
