Nice video mate!
I already said this in my YouTube comment, but I'll elaborate a little more in here:
I think the first Shubibinman game is terrible, its controls are awful, it's barely even playable! It doesn't help that the graphics are bleh and the music didn't stick with me even a little bit...
The 2nd game I think is WAY better than the first one, but that's not a very hard thing to accomplish... The controls are okay, the game is at least playable now, but the game's design is kinda crap, both in the level design as well as the game's structure, I mean, is there anything more annoying than having to watch the same unskippable cutscene Every Single Time you die? And you will die often! The game is way too hard, and not for the right reasons...
It at least makes up for that with some really nice graphics and music, I'd say the 2nd game is worth it for the presentation alone, and I do mean for that and that only...
The 3rd game I think is a fun and playable Tech Demo, but not much more than that... It's WAY too easy for its own good... It's certainly worth experiencing because holy crap is it impressive! I mean, look at how many scrolling layers they've squeezed out of the system! It's amazing! But of course, that comes at a cost of Level Design, which is pretty much non-existent in the 3rd game... It has a lot of fun set-pieces that show off what the system can do, and the cutscenes are pretty too, if way too long, but yeah, it's all just a glorified Tech Demo...
I haven't played the SFC game at all, so I can't comment on that one...
