New v0.2b UPDATE:

• Modified player collision
• New weapon
• Map modification
• Gamefeel
• Better sound and OST optimization

Modified player collision: Now the player collision is smaller and helps to be able to escape from the enemies and that they don't kill the player when they are far away. 

New weapon: Now in addition to using (X) to shoot, you can use (B) to shoot a shotgun bullet. This weapon has a 0.45s reload.

Map modification: In v0.1b players could often hit the top of the upper platform when jumping between the two ditches. That line of Tileset has been removed.

Gamefeel: Now when shooting, the guns drop bullet shells.
