They can shoot my foot when I am above them.

The portal isn't very intuitive, I expected things to come out of it in the opposite direction. I also kept getting stuck behind it.

VERY NICE game!

For the level before domino, what is the intended method of getting through the top right portal? The only way I could find to do it felt glitchy, kind of wiggling in place until the portal let you essentially walk past it.

The boss once glitched up on the left block and kind of teleported.

Having a boss health meter would be nice. The game has a ton of potential, but the boss is very frustrating. The game goes from feeling like a puzzle game to feeling like almost complete luck due to the random boss motions. Also, the boss won't shoot when you're on the blocks above...unless they have spotted you, in which case they will keep shooting you in the foot while you can't shoot back.

Without a health meter I don't know if the boss needs 5 shots or 20 to kill, and I don't know if the boss backshots are actually hurting the boss, or if the only way to damage the boss is through normal shots.

Having some sort of onscreen indicator that shows when you can use the backshot again would be really nice, so you don't get killed through trying to use it too soon.

...after playing further, apparently backshots DO hurt the boss. I died at the same time, but the game apparently counted that as a victory.

Long story short, I think this is a funny and awesome idea, and if you fix the boss level and some of the glitchy-feeling physics, you could make something really neat out of this!

Also I forgot to mention, having portals color-coded would be nice, if possible, instead of having to figure them out through trial and error.

This would probably require some level redesign though.

Neat game, though I feel like you could make the shooting a little slower - maybe slowmotion once guns are fired?

This is one of the better ideas I've seen so far. Well done!

Very creative interpretation of the theme. The backfire mechanics were interesting and the portals added an extra layer of complexity to the levels. On top of that, the music and visuals created a nice atmosphere.

Very clever puzzle game play, nice interpretation of the theme. Great work!

Stood on a guys head, he wasn't even mad.

I enjoyed the time attack, nice touch.

I really like the idea behind, I think it needs a lot of polish, but man, is quite clever, you could extend this idea further on. Good job.
