Oh no no no, don't get me wrong! I had fun! It wasn't negative experience at all :)
The slidiness made it really hard from the very first level, which is what gave me the rage game feel to begin with. Didn't mean it was bad in any way!
Ok, I'll have to try the graviton level again, didn't have much time to play around in the first testing of each game!
All in all, I actually did mean that it was a great game :)
