Warning: I am clueless and don't know much yet. If someone tells me I'm an idiot and completely wrong, listen to them.
But with my understanding of how programming works, I'm pretty sure it wouldn't be file size, it's probably some bug you accidentally introduced with the extra work you did...
For when I start building my own system instead of just tweaking the tutorial setup:
My plan is to make everything ratios between two opposing stats to keep it simple (at first, anyway). You can think of your attack's damage as the opposite of HP.
So the number one complaint I get so far is the levels are simply too large. What's funny is in testing I deemed levels taking too long and actually shortened them. Figuring I could beat them in 5-6 minutes so players would be able to do so in probably double that. I was apparently very mistaken, only one player has mentioned even reaching the second area. Let alone the first boss.
I don't believe it. I actually did some proofreading in my game - and fixed some grammar errors! I feel so accomplished, knowing I can actually proofread my own writing!
...I've had a bad day, okay? Bad enough for me to want to proofread stuff.
Ughhh, July is not my month. Thankfully, it's nearly done.
