Hello, I tried out your game for a bit. While playing through the tutorial, I wasn't able to get past the first column. I tried holding space to jump, but the character doesn't seem to get high enough to get past the column. Also, the default control scheme of WASD + space to jump feels a bit unnatural to me, the option to use Up/Down/Left/Right and space would be nice. I also noticed a significant FPS drop when entering full screen mode in browser play, although this could be a problem with my machine. I like the fun designs of the main character and some of the enemies!
So a friend and I did a few tests on that section you are talking about. 
We were able to get on top of it.
My friend said "You have to hold the jump button basically while right against [the column]"
Can you give it a try again?
If that doesn't work, can you let me know some details:
- Your computer's operating system?
- How much RAM your computer has?
- If you have trouble reaching any columns of that height outside the tutorial?
This way, we can see if we need to optimize this game better for certain machines.

No luck on a retry.

I'm using Google Chrome with Windows 11, with 64 GB RAM, it seems like the character has approximately the same jump height outside of the tutorial but can't totally tell. I do have hardware acceleration disabled in Chrome settings because it doesn't play nicely with my Intel GPU, blindly speculating, but it's possible that's a factor in the behavior I'm seeing.
