The arcade was amazing! It spoke even by its floor pattern! And then after playing 4-5 times I saw there was another room on the top floor! Well done!
The enemies were great and especially the sounds they make! (I kept hearing a "yipee!" sound and I didn't know where it was from but it was super funny!)
I have to agree with Ludicorde, I couldn't appreciate 100% the ammo types, so to read them all I had to hide on the top floor behind the counter when one or two enemies were left.
I have no experience with 3d to ask how you pulled all this off, but I was curious to hear about the menu systems and how you made the sliders actually impact the gameplay.
Have to go shoot some cupcakes to thirsty bats now, sorry.
