Here are the changes for the second build (let me know if I miss any, my brain is all over the place when I work on this)

-added animation/sprite changes for attacking, hurt,  and death for the player.

-added animation/sprite changes for walking and hurt for enemy.

- player now falls to the ground when all health is lost instead of disappearing.

-added a small light effect above blue grass idk (yes that is the placeholder name)

-slight improvements to the code, however this most likely isn't noticeable in game

-updated textures

-the first tunnel's ceiling is slightly taller

-health texture is easier to see after being hurt

-funny guy's pants are now more dull (yes that is the placeholder name)

-taskbar and window now have custom icon (I did not feel like figuring this out in the first build)

-updated sound effects, I hope to have the footsteps sound fixed in the next build

-should be slightly more fun and tolerable 

please let me know what you would like to see in the next build, or if you've found any bugs. thanks
