I really do like this. I think the music, animations and backgrounds etc. are all really good.
Only 2 things I'm not keen on:
1. The bombs that sometimes fly in out of nowhere and kill you. They feel like cheap deaths because, really, the only way to dodge them is by simply rolling whenever you're not jumping over a mine. Maybe just make them 50% slower so that the player can see them as an obstacle and have to react? I think they're just too fast and unfair at the moment :P
2. There's now so much text on screen :O Perhaps you could reduce the amount of score counters that show up in the foreground so that they only show at certain milestones or something? Or just make them appear less. They often get in the way as you have to jump over a mine. Or put the new text bar higher up and out of the main way. Just feels a little cluttered at the minute with all the numbers and text I feel
Other than that, I think it's dead addictive and a cool Oddworld fangame. So keep it up!
