Thanks for your comment, CTRL is a sprint and can go through some obstacles.
Great game, it made me know it's not the spaces that make me unable to jump when I'm playing,It's that I didn't press it, although I don't want to admit it.╥﹏╥
Your advice about Unity was very helpful to me, I didn't know about it before this.
Thanks for the suggestion, my friend also asked me about the resolution
I'm so sorry, this is my first GameJam,I ignored the latter after I saw that there was no theme.
