Nitro Ball (US)

0.68 [Bryan McPhail]


Bugs:

- There appear to be some priority problems. You recognize it when you have to shoot a door to get the next area the first time. go close to the door and the door is over the player, which looks weird, also there is a little glitch in all the text layers (see snapshots). Updated by robiza in 0.108u3: The text layer glitch bug is fixed. nitrobal068gre Firewave / robiza

- turn on flip screen dip then watch the attract mode and the graphics are not correct. nitrobal0111u5gre Speedfreak
