Unit 2 project

Name: Jiahao Zeng
Bug:  attempt animetion, but broke the game(can't move left or right)
Pass through blocks if jump
Stop any horizontal movement when reaching blocks
sometime stuck in the middle and sovle by click more times or move with other direction
game crack when game not finished and click the flag
only able to jump once on the block 2(custom problem)

note: Level 2 have 1 less block, arrow move in small shift so...
Techniquely possible to don't pick up gun and kill no enenmy to finish the game, a some how harder way of game(I done it, so actually possible too)
