really good game, but a bit short
I think the idea is very good its not a portal clone, it has its own logic. Some levels are really tricky but remember when you are in air and a portal is on the ground beneath, you slightly outo-aim while falling. When it says bounce bounce bounce don't try to do it with the arrow fields but go up and down on the first block to gain speed.
P.S. the pigs are sometimes abit "stupig" but you can solve the last bonus level without them. Just bounce bounce bounce ...
