I am glad you liked it! Imagine that I have to add 3D sound, in order to know from where exactly how hear the howling (now you are a bit lost without this), damage display to the enemies (NOT health bar, but just numbers that indicate how much damage you have done) and then you have to understand how much HP does each species have, a health bar for the player, in order to know how much life has after every hit, more species, fix some things that bother me a lot and generally make add more features such as a menu, a starting image and other stuff that in the end will make it a full playable game, ready to be released.
