Overall, not a bad game. Some parts are rather difficult, though that is to be expected. Not a huge fan of unkillable enemies but it adds a different dynamic to the game. I think this is a pretty neat concept though.
Did encounter a glitch with the first 'boss' that worm thing. It didn't load the first time I played through. I started over from scratch and it loaded the 2nd time.
Keep up the good work :)
