I found this game quite appealing. It doesn't start off too difficult - it does a good job of rewarding players for trying it.
Although the game does impose a controller profile, it does (at least) come with the ability to edit "data/controls.ini". I would've preferred the game to have a built-in keyboard or gamepad toggle, but at least the INI file option is there.
Even if you disable the imposed controller profile, the game will still impose on the d-pad. This is quite common. It's not a huge deal to me. Lots of games impose MUCH more, so in this case, I'm thankful.
There doesn't seem to be a way to automatically maximize the screen. Additionally, I assumed that Alt-F4 is the right way to close the game. Alt-F4 was not included in the Game Controls list (above).
I know I'm being nit-picky, and honestly, this was a great game overall - I'm only bringing it up because there's a certain kind of perfection this game would have, with these extra provisions.
