Glitch 1 is fixed.
2 is on low-priority. will be fixed later.
3 is low (not game breaking in anyway, and twilight is unicorn. Why not walk on water? xD)
4 is actually it is a secret to help people level up faster. I don't think I will patch this because you got teleport blocked during so. So.... players won't out farm anyone. (glad, you figured it out )
5 ...
6 That shield is OP. So that achievement is supposed to be tricky to get.

The new exp based system is better and much more powerful. You can stack equipment exp in multiplications and max level of 150 and each level increase your item's all stat by 10%. That makes a weapon with 10 attack to have more than 150 attack if it reaches level 150.
Furthermore... It got same upgrade feature as before when item reach level 5 and feature effect is very OP.
It does take sometimes to get used to this "better feature".

Keep the bug reports up
I will set up a reward system soon. For beta testers.
