I done it!
Cute game, great looking menus! I liked the gameplay for what it is, there's a good balance between your movement speed and the enemies, BB gun seemed way too powerful, until i've found other weapons, which were fucking nuclear in comparison.
Took me way too long to wander into a girl or a new weapon, you might want to add a minimap or something that will guide the player.
There's currently no reason to not hold RMB all the time.
Keep at it, i always enjoy seeing your progress, adding enemy variety will make this great!
