* GoddamnedBats -- The X-Box Arrange Mode adds numerous swarms of bats from every single direction, solely for the purpose of increasing the challenge.
* PortingDisaster: The Platform/XboxLiveArcade port runs in letterboxed 16:9 if you are using any resolution that doesn't have a 16:9 aspect ratio (i.e. a standard-ratio CRT screen), on top of the pillarboxing used to fit a vertical screen onto a horizontally-oriented monitor. So unless you have a huge widescreen TV or are willing to turn your screen 90 degrees, prepare to play in a VERY small screen.
* ScrappyMechanic: The coin chaining system. It would be more forgiving than ''VideoGame/DonPachi''[='=]s {{Combos}} system, but it has one major concern: Your coin count ''carries between stages.'' So in order to obtain an optimal score, you have to chain '''the entire game'''--a broken chain can spell RageQuit.
