Hi guys,
Muzboz here. Great to hear many of you are enjoying it!
I've submitted an update v1.1, which makes the first level easier, so you get into the action faster, and also speeds up the intro sequence. The load times won't be fixed for a little while, but they become less annoying after you play a few times, and each play-session last longer.
You can checkout my Rad Skater Trailer here, which gives a quick look at the stuff you unlock as you get higher scores.

I wish I could have improved the load times, as they are a pain. I built the game in Game Salad, and I know it gets a bad wrap sometimes, but I tried really hard to optimise everything as well as I could.
Game Salad was the element that let me leave my job as a Game Designer at Firemint, and start (finally!) making my own games.
Game Salad are soon to release an update which vastly improves load times, by removing their intermediate scripting language (LUA), and making it native code instead. Hopefully it comes soon! Alas, it was not yet ready when I released my game. But I will update the game as soon as they do, and I think the load times will disappear.
In the v1.1 update (should be out in a few days), I've also made the start of the game just a little easier to collect the first round of mix-tapes, so that you quickly unlock the Zombies, and after that, the Synth Blast, and the Invaders, etc, and things really speed up and get a cool flow happening.
You get used to the flow of the game, and each session generally lasts a few minutes, and the load times really don't become such an issue. But they are certainly annoying when you're first playing, and die-ing a bit more often.
Please do give it a go, and persevere for a few goes, and you'll soon have unlocked the Synth Blast and the Invaders, and the whole flow of the game is picked up and much more exciting.

I promise!
I have lots of other game ideas on the go... a stealth adventure game, a detective word game, a blaxploitation zombie game. So any support is much appreciated, and I hope to bring more fun games to you all soon!
