Such is the nature of bugs, they make no sense whatsoever. I'll let you know if I find anymore, although at the moment I am stuck so I could use a hint, I showed a picture in my other reply!

I did manage to fix the bug , somehow there is a pixel gap in this specific location on the tilemap , its not a problem with my code or collision , its just a small weirdness that happens on this exact tile , the same thing doesn't happen anywhere else, and if I change the the two tiles below the fall it doesnt happen , now I'm scared that there could be more places like that
for a quick hint :
try going into the cave and jump down to the lowest point
Okay I got the tank powerup and went to both places I assumed the final boss would be, and both times I got a max health +50 and one of them I got a jump boost. Now I have 200 health, 5 jump boosts and I feel like I have explored the entire map but I have no idea where the final boss is supposed to be.
