graphic on my work computer (which is not that powerfull)

-screensize = 1.5 => ok
-screensize = 2 => very very laggy, unplayable from my point of view (how the hell is it possible to have a slow scaling in our days...)
-no fullscreen (!!? wtf, we are in 2014, not 1990)

controls
-cannot customize keyboard (!!!? x2 wtf once again. Are we going back that much in time ? )

-gameplay
it's raiden, don't expect to put much time in this game

-price
8.99$ or 6.79€, is still a bit expensive for what this is. Should have been 4-5€ at most, i feel a bit upset for having bought it.
nice for playing 5minutes when i don't want to work though. But i really prefer Desktop Dungeons :)

so finally, i think you should wait for a lower price. Funny to see that for steam, 8.99$ == 8.99€, thx gog for that at least

You modify the controls in the config utility and set full screen in the config utility.

oh thx, didn't though the config would be external.
Fullscreen is black on my work computer though -_- sound and keyboard is working, but black screen.

I suppose my home computer will work better ^^

Man, I've been playing the Raiden games for years. Sure, it only takes a little time to see the ending if you credit feed, but getting through it on one credit and with a good score isn't exactly something you're going to do an hour after you buy it.

Many japanese PC games have a external setup program.
its just something they do
