tinyE: The retro graphics don't bother me, AT ALL, it's the lack of originality that can get a tad trying, and that's kind of the point I got from the OP. 8 bit with some CREATIVE gameplay would do wonders; if I find myself in another fucking castle looking for another fucking princess, buying potions from another fucking old man in a cave I'm afraid I may have to shoot myself.
Kunovski: I'm pretty sure the Hammerwatch was the trigger for him :)
and I must agree that this game looks so dull I didn't even finish watching the trailer...
but look at Rogue Legacy for instance - it has all the attributes you've mentioned would kill you, yet one can rarely find such a great platformer with a constant "one more try and I'll go to sleep" effect (and I don't like platformers, the last one I enjoyed was Cave Story)
Funny thing is I'm very seriously considering getting Hammerwatch, just not at 20% off. I can wait.
