New Game - Testers Wanted

HO HO HO, MERRY EASTER, EVERYONE.

Sorry I've been a bit dormant over the past week(s). With uni and whatnot I've been a bit pre-occupied (ok, that is barely true... I only have uni 4 days a week). I've been learning ActionScript 3, and I mean really learning it, not just mashing together a bunch of code from tutorials and hoping it works. I'm using Flash Builder instead of Flash CS5.5, so I'm working entirely in code and I think I'm better for it.

Anyway, I'm making a platform game, and the idea is, the player is plonked into this world full of platforms of random sizes and positions, and he must run across the platforms as fast as he can, while being chased by a deadly laser to his left (the laser will cover the entire height of the screen, so there is no escape other than to keep running right). The game is based around Murphy's Law in that, if there is any possibility of something bad happening (no matter how unlikely), at some point in the game, it is going to happen to the poor old player. Call it Hell, if you will (without all the violent stuff). So, this means there may be the occasional flood, where the player must swim (slower than running) or jump onto the next row of platforms and perhaps be pummeled by a shower of flaming meatballs. You get the idea The aim of the game is just to survive as long as possible. It will keep track of stats like time spent running, time spent crying, meatballs dodged, calories burned, etc...

So far, I've been working on the physics and platform generation code. No visuals are in yet, so it is just the player (a rectangle) and a never ending array of platforms (also rectangles ). No laser yet. The platforms load in chunks of 4, so once the last platform enters the screen, 4 more platforms are generated just beyond the screen. Once the last of these enters the screen, the first chunk is dumped and the third chunk is loaded. The cycle continues, so there are always two chunks loaded at any one time (apart from the start, where you have just the one chunk).

Here is what I currently have. I'd like your feedback on the kind of performance you get and what hardware you are playing it on (gaming PC, normal PC, laptop, netbook, tablet, etc.). There is an fps counter in the top left. Ideally, it should be a solid 60 fps. Oh, controls, in case you lack the confidence to work them out, are the arrow keys.

Very shortly, I will be attempting to add another layer of platforms and that laser I was talking about.
