Now I don't want to be a spoil sport and I totally dig having another event, but there's something that bothers me.
Remember the HUD skin from Halloween event? There were some issues with how they were designed, and I'm afraid you've done it again.
When you take damage in PSO, your HP bar will turn red briefly for the amount of damage you took, so you'll always notice when you took some BIG damage even if you don't look directly at your HP bar because you will certainly see that big chunk of red colour in your peripheral vision. With the Halloween skin, your actual HP was shown in a muted shade of green making it hard to see. Now with the current skin, while the HP bar colour itself seems fine, both TP and HP bar have a huge red stretch of colour beneath them, again resulting in a somewhat difficult colour combination.
The repeating colour gradient in the game menus (weapon/item list etc.) also is somewhat eyestraining.
Please don't take this the wrong way, you've done awesome stuff so far with the server and I have a lot of respect for you guys but please try to make the skins a little more eye-friendly.
