incredible game, well done.
First of all, despite the fact that this episode was incredibly difficult, it seemed a little more manageable than episode one, for which i am incredibly thankful. I'm not sure if you downgraded the difficulty on purpose, but either way, its a plus (more savepoints too, which is great). I love a difficult game (as this is), but there are limits.
Second of all, the relics seemed easier to get on this one. They weren't incredibly obvious, but the hints seemed to me to be more noticeable in this one than in the last, so well done there too.
The boss was really tough, but there was a pattern to him, and once you figured it out, it is possible to beat him.
I only have two suggestions for improvements. First of all, there was a minor bug, i'm not sure exactly when, but it's around one of the purple checkpoints (i think its the first one). It's just before you get the beast egg relic. I walked across a screen into the next one (on the path to get the beast egg), then decided i didn't want to risk it and went back... and the screen i jumped to wasn't the one i had come from.
Also, if you could add medals, that would be great.
Overall, can't wait for the next game, well done.
