Regarding the item bubbles, I did that to make it more original. Less Mario-Like. It used to be the typical ? block you see in Mario games.
I don't understand why it says Up and Down. Also, I can't make it say X. Because PB allows you to customize your keys, I say, "[use]" in the code to make it say what I want it to say. I checked and double checked my game, and it says itself that it's ALT. Since ALT is my use key. And, I'll need to know where that sign is. I was afraid some of my signs were out of date.
As for crowded graphics, this will get fixed down the road. I've learned that less is better. My poor level design I believe has improved. My new levels and levels I'm completely redoing will not have this issue.
As for the orange enemy and explosions, that is because this is another thing I fixed in the update. I don't understand why it's still showing an outdated version. TingThing sent me an e-mail an hour or 2 ago at the time of this post verifying that it had been updated. So for it to also not show the enemy's projectile which is a box that detonates on impact, that tells me that that is another problem I resolved the other day.
What is wrong with the pipes?
The music is a WIP. I had been using Kevin Macleod music before, but I'm wanting to do my own. I'm still struggling with writing my own music. I can write music just fine, but for the forest theme, IDK what kinds of instruments I want to use.
