the portal level was to introduce you to portals :) I tried to make it a bit challenging without distracting you with a bunch of other mechanics. I tried to keep it from becoming too frustrating, at least in the first few levels (I did get a bit devious later on), but I didn't spend enough time fine tuning them. Probably, after voting is done,I will redo the levels a bit. BTW, if you take a systematic approach at the portals, you will reach the exit in a maximum of 43 jumps, as little as 3 jumps once you know the correct portals.
