These seem to grow on trees.
Anyways, another one game special.
It says:Pay what you want for the Voxatron alpha and...

Be the first to tackle this voxel-based, old-school-gone-new platform shooter. Pick up your trusty pea gun and shoot your way through more than twenty areas filled with blocky baddies, destructible toys, and palliative powerups.

And soon, Lexaloffle plans to add monster creation tools for designing your own blocky bad guys to populate your creations.

Personally, Ill be buying this.
Its also got a pretty sweet level editer.
The gameplay is rather unique & it reminds me on Minecraft.
That's always a good thing.

I bought it, beat it, enjoyed it thoroughly.
That voxel stuff really does add to the experience, it's quite fun.

¡ Remember that Australian engine that runs on voxels.
They are the future. Not polygons.
This could be considered a success!
EDIT: Duh, you say you finished it, how long is it?

That engine runs on sparse octrees, not voxels (notch actually talked about it).
Though there are some sophisticated engines out there like Atomontage that are voxel based, but it's most useful for destructible terrain versus characters (which are better done with polies) since terrain doesn't have to animate that much, only be modified and then stay static.

Played through,

Uh, it took me about a half hour iirc, not that terribly long. There's 4-ish areas, the first one directly in front of your initial spawn, one to the right, one to the left, and a lava area that branches off from that one, and then the end.
Quite vague directions I know but I have a terrible memory for small details like the theme of each area.

Bought it reflexively, I may only play this for it's voxelyness.

Hum hum, made a commentary, it sucks, I know but check it out ^^
