I found a secret: When you enter the game, the monsters walking at the title is random. However if you enter any level and back to title, all of the monsters will be the last monster you met.
Ace on Level 4 is not possible because it requires to let mouse out the screen, however it no longer works.

For the last comment, I mean the Wisdom skill seems useless, because it increases the EXP the player gain but every time you upgrade a skill the EXP cost will increase too.
This time you do not - me, Please?
