First status-report: Mechanics are down, now I'll have to make it not look terrible. At least there's still plenty of time.
Some boilerplate-dwarves with interchangeable heads, also here's a flat-shaded one.
I might be giving the theme, I'm going for away here. ;)
Yeah, and imgur-links



Progress 1.
Hey, reading your post now I found out that my idea is not original at all, but oh well, I already started. By the way you guys are doing great stuff.
So, my game is about defeating zombies before they touch you. By rotating the mirrors to reflect the light beam. Your attack damage increases with the amount of bounces.
I already have the programming part done. I still need to work with the zombies pathfinding part tho.
But I just started doing some art with magicavoxel, and I thought I could post some basic progress here.
Hope you guys like :D, sorry for my english
I think I'am going to post my progress here aswell :D
My first Idea was to make a story based game where you are part of an indian tribe that thinks that if you look into your own eyes through a mirror, you get traped in your own soul. Some day you accidentally look into a mirror and you get traped in your soul. There you need to fight your inner Evil so you can escape from there. Sadly that Idea is too big to do for me because I didnt got so much time this month (lot of school etc.).
So I now made a much simpler game, inspired by the old "Asteroids" game.

The game concept is the same: Shoot the Asteroids. The new thing is that the lasers you shoot get deflected by the walls so you need to be careful that you dont get hit by them.
The Movement, the shooting, the reflection and the basic asteroid movement is finished. All the art assets are not yet finished and are only prototypes.
Looks amazing!
But u mentioned it took too long, so i got a little tip for you (you can use it or not, depens on what u wanan focus on and what u want to create in terms of game mechanics), which u already at least partially got yourself.
Keep the artwork level of items that do not have an actual function, like just standing around, low and put the time u gain into the important artwork (game chars, enemys, items u can actually use), because changing these later on can be much more work, than just changing some assets that have no function in terms of gamemechanics.
Idea: You are a 50s-70s James Bond-ish character and you have been sent to assassinate an enemy following a line. (With maybe a bodyguard?) And you have 30 sec to place up to {An undecided} amount of mirrors with the ability to ricochet your bullet. After that time, the target follows the invisible line and you lose if he is not dead by the time he gets to the end.
Help: Anyone have an idea for a name, I was thinking a 60ish spy movie title like 'The Vanquilizer' or something.
(This is my first game, and jam)
Thats a neat twist to the reflecting mirror ideas that a lot of us have. I like it a lot! I think you can make the environments progressively crazier (like using mirrors to ricochet bullets off other objects in the world, etc).
Tbh, I wouldnt worry about the name yet - get the basic mechanics working first and a name will come! (At least thats what Im hoping because I have no name or story for my game lol)
New progress update for my project is now available as well.
"Mirror Escape" Dev log 1: first successes
This also will be my first game made with Unreal Engine 4. I must say, using its C++ interface feels like traversing a very convoluted maze. Blueprints on the other hand are very easy to use and fast to learn. Not everything can be made with them though :(
Also if someone wants to help me with creation of 3D assets, I will be grateful. I know how to use Blender, but i'm not an artist by any definition(just look at that hand model :) )
Update 5
This should've been uploaded 2 days ago but I had to resolve some issues with my account. So this is my progress, so far..
You play as a spider that can teleport by shooting lasers. Kinda inspired from the Geometry Dash spider. There are also mirrors that reflect your laser, which enables you to reach other places you normally can't. There are other types of surfaces that you can't shoot your laser on, and this is where mirrors come really handy. This is all that I have at the moment, I'm still adding more puzzle-y elements to the game and also more types of mirrors.
Also I'm having a hard time coming up with a name, so if you have an idea, feel free to suggest.
Update 3
So I had some more spare time so I managed to redo my sprites, still missing a parallax background. I'm pretty happy with the look now so I'll keep moving with this style.
My coding time was dedicated to moving the level editing to pixel colour recognition, allowing me to design levels in photoshop, and better handling of intersections for the anti grav. Still on the mechanics to do is cutting and removing anti grav panels (looking forward to the fun math on optimised mesh triangles :)). I'm not sure yet, but I might do some basic enemies if I get time (patrol and shoot/chase within range).
Here's the vid:
