The last level is possible, you just need to run off and time your jump perfectly. Took me about 8 attempts before I was able to reach the far platform.
Over all a great game, easily 4.5/5. The only thing is in the wyvern's description it says that wyverns do not breath fire like their dragon counterparts. But, the animation for the wyvern in the pen clearly breathes frequently. Just something I noticed while I played.
Overall, this game is so utterly intense and is easily my favorite game on kongregate. The fact that you can go back and buy the omega items makes the game so much more fulfilling and adds a huge replay factor. I especially loved the God of Penguins saying, "I command you to rise from the snow and fly some more!" After you crash going 1000+ mph.
