New Update \^0^/

Hi, everyone.
After a lot of small update for the last 2 weeks,
I'm glad to announce the new version of the game.
Here is a summary of it.
- Add difficulty option. Now we have Easy, Hard, and Explore mode. Easy mode is recommended for the new players. The hard mode should for retro gamers or players who has confidence in their skill. And Explore mode is for practice or explore the stage in hard mode.
- Adjust the jumping system, now the player will feel easier to control Ascii.
- Adjust a lot of game balance in every stage.
- Fix bugs.
