Oh hey, thanks for the feedback! (also its never too late for feedback, I didn't want you to feel obligated or anything to drop any, sorry if I made you feel pressured!)
Do you know which pits in particular are giving you trouble? I can look into improving that part of the level design for better distinction. I am also planning to make Gems easier to acquire in the future, I might lower down the weapon/shield prices a little bit and also reward people more gems if they've clear the challenge score. I'm glad it isn't just me feeling that (I often worry if I make things too easy so I tend to overcorrect).
Lastly, as for ladders, was there anything in particular that made it difficult?
For the saves, did you extract the game out of the zip file? That's the usual cause of it not working since files don't get updated inside zip. But if that wasn't the case, I'll look into what's causing the bug.
Anyways, thanks! I'm excited to keep improving the game for everyone. <:
