The Lonely Castle Crasher Entertaining.
This was a really good polished submission and I was happily entertained. The beginning was really slow and I personally thought the flash was going to end stupidly or with a shit punch line, however you did quite the opposite, at half of the flash I thought it would stay slow, but the end had a really good twist that made it worthwhile.
The cute sounds the crashers make are adorable, that's why I watched this numerous times just to listen to them, the best lines were possibly...
"I'm all out" (there was a tone of sadness in his cute voice)
"I'm gonna crash your castle all night long" (sounded humorously kinky)
The art was brilliant and well polished, I'm surprised you did the art all in Flash without any help from any other program like Fireworks, awesome job on it, it had a nice cartoon style just like the real castle crashers.
The only downside was the painfully long slow build-up which sometimes puts me and possibly others off watching it again or watching it all. However like I said, the ending made it better.
Overall, brilliant well-polished Flash.
