This is a fantastic achievement for a ten-day project! I've made a video of my playthrough below:
As far as my thoughts on the game, this is an awfully faithful rendition of Quake, as you have aimed to create. I hope there is a big appetite for these sort of games - I can remember people addicted to these in the 90s!The core mechanics are very well fleshed out. All the fixtures are here: weapon varieties, enemies, ammo/armor/health packs, interactive doorways and platforms. The foundations of this are executed so well!
Gameplay is great. Notwithstanding some early issues with ammo, this is chock with pumping shotgun slugs at enemies constantly. Super satisfying. Does the damage model differentiate for headshots or am I imagining?
In terms of moving forward, I think for flavour some greater variation on the texture design could help. The limited palette of Doom and Quake was out of technical limitations - you have the potential to go even further!
It'd also be nice to have some music like the menu music ingame - I remember the soundtracks to the FPS games of those era always being quite intense, moody ambient music of this game being a counterpoint.
Great work on this! I hope you keep it up.
