As with much of the game, the combo interface needed a little more work.
Finished today, in 9 hours (but with some sightseeing on the levels). Overall I liked it, but as other have mentioned, during the whole game I got that feeling that with a little more budget/work you could push this game into something really special.
The combo/pressen system is interesting, but the execution has some serious flaws. Maintaining the combo going doesn't feel very... "fluid" and in the end you just choose one of the bigger combos and try to finish the sequence... each time for very enemy. Sill, the idea of assembling the effects is nice, and maybe with a more dynamic battle system with more targeting switching (like Batman AC/AA) with shorter combos and less powerful pressen (specially the health regen) it could be a lot better. In any case, it needed more tuning.
The game could also use a lot less linear levels. Specially with such a interesting world, I really wanted to explore more. As it is, there is very little interactivity and you're always on rails, with very few exceptions in small "detours" to get some collectibles. Even when using your tools to more some things around, since you basically just trying to "align" the elements to move forward, it doesn't really add much.
That... and the camera, are the bad parts. The rest I really liked. The art is amazing, the music unique and great and even if the story isn't that great, it has it's moments. The remixes are interesting and even if there are very few I think the quantity is okay, since they are basically try-and-error by toggling the "switches" you can change. Plot wise, they made me feel uncomfortable, specially the last one, but I suppose that was the intention.
In the end, the flaws weren't enough to sour the game for me, but it will depend if any of them gets on your nerves (and to be fair, I'm more forgiving when the game is at least trying something different).
For me, it had "serviceable" gameplay, with a very interesting world, beautiful art and music and decent story. Probably not enough to justify full price to most people, but to keep an eye on when it gets on sale.
Would be really nice to see a more refined and expanded sequel, but I'm guessing that it is very unlikely...
