I could clip through the walls and it felt like I shouldnt be able to do this. Maybe I was missing something.

I was able to clip through everything, and nothing made a lot of sense. Maybe the monster was inside me the whole time?

This happened using Microsoft Edge and Chrome browsers also.

Very laggy (even on my i5-4460 and GTX 960) and I could walk through the walls. I couldn't find the monster.

I think you're out of the theme with this game.
I had some exception.
Keep working on your game ; )

I got this:

The graphics are sweet! Shame there's not much game here though

Great graphics, though I'm not sure it's working properly - was very stop-start and I'm not sure what I was doing.

Still, really cool art, not seen anything like that!

Love the graphics style, there just needed to be a bit more game.
Also why couldn't you play my game?

Cool graphics and when you just accept that you are supposed to walk around in a jerky way it is actually quite enjoyable to walk around. Gameplay a little lacking.

Thanks for everyone trying the game. The drawBuffersExt is known problem, the mirror needs fbo support, and older chrome doesnt have it (but works on some versions of chrome). The IE or edge has never been able to run the game :(. But anyway, thanks for people reviewing it.

Not really sure what this is. The shader is awesome though. You should make a game with this! :D

I think that its very interesting how the game looks and hows it is displayed. Good job!

It's basically a demo of the 3D graphics but it looks pretty interesting, the lighting and reflections are impressive anyway.

It's a pretty good tech demo. Very pretty. But not much game in here at all.

Doesn't work for me on safari/osx. White screen only.

Definitely more of a tech demo - pretty, but uncontrollable and barely any gameplay.

Exception thrown to the console :(

Wasn't loading for me.

Did you develop the engine ?
Nice work if it is this, work fine for me. (win64 firefox)
I just didn't find any monsters ! :'(
I looked everywhere, even inside the object ! ^^

@LeoM: yes, the engine/library(GameApi) is developed by myself. The monster is inside the mirror.

The game looks quite interesting, but controls quite awkwardly. Definitely has the tech demo vibe.

Very interesting from a developer standpoint. I would like to read a post mortem of it with some technical insights on emscripten and the type of rendering used in this.

here's the requested post mortem: http://sivut.koti.soon.fi/~terop/world_postmortem.txt

"Exception thrown see Javascript console". That was all it said (console was empty)

Thank you for the post mortem :)

Not much of a game, seems more like a tech demo of some kind. Graphics look... interesting, but there's not much to play here.

The graphics were good but there wasn't really anything to do aside from walk around (and through stuff).

Is it a raytracer in emscripten? Neat! Not much of a game though...

Coool... Thank you for the source. Will find a lot to learn. Thank you.

I really liked the art style, and the graphical elements were consistent - but, could walk through everything, and nothing seemed to "interact" and was very laggy. I never found the monster. :(

no errors but the wasd movement could be done smoother :), suggest reading keyboard input in the main loop and update the position by smaller increments would convey that. with some help from the author and the mirror I found out that I was the monster all this time! good job getting emscripten running

I updated a little the platform support. Now microsoft's edge browser should be working too. And drawbuffersEXT problem is solved. (chrome and firefox was already working before)
