Hey :) Thanks so much for the positive feedback - I'm really glad you enjoyed it! There's a secret on the other side of the lava, in case you missed it ;) I used graphics from Quake, but also from modified texture packs for Quake. Higher resolution, fan-made stuff. I think the original graphics would've looked blocky - and besides, I couldn't rip from the original tga to png easily!

As for Construct 2, yeah, it's a bit disappointing that it doesn't make exes. Even html 5 stuff doesn't really work offline, so I'm forced to host it and have people play online, using certain browsers. But the engine and tool is solid. Yeah, the rolling physics sort of comes with construct 2. You have to enter a few settings manually, and assign certain physics forces to the keyboard keys - but as you can see it works without too much trouble. There's a rolling physics example level that I found really helpful. Of course, they also do 8-direction and platform controls as standard - without the manual configuration. but I figured rolling physics platform controls made more sense for a game like this :)
