The game looks very promising at the beginning, but it quickly falls off when the tutorial ends. I personally enjoyed the looks of the tutorial much more, than the actual levels. I have to agree with others that lack of feedback, and a very weaird fx of player shooting, that also lacks any feedback of hitting the target is making the game really hard to enjoy. Sometimes rewind was straight up useless, especially when you start shooting the turrets while the text is still on screen in first levels. I also had some motion sickness in the first "elevator" and had to look away from the moving part, but that maybe just me.

I will say, that despite the above, the game is quite impresive in execution for a game jam game. The movement feels nice, the rewind works with a good feedback of how the player is rewinding, it's just a shame that little things like no indication that you're being hit, no way to dodge turret shots and so on can ruin the overall feeling of the game, and I would also really enjoy it more if you stayed with the tutorial-look, but that's subjective.

If I have to point out one thing that stood out to me from this game it would be how the music rewinds with the player, that one little detail is great. 

Hope feedback from me and others will help in improving the game. Good luck for both this project and any future projects.

Yo’ Templar here,
While the main mechanic is fun, the lack of player feedback, when shooting, when getting shot, makes the game difficult to enjoy, the turrets just start barraging you with their aimbot the moment you step near them.

Very nice idea. I liked the story behind it. The graphics are simple but polished. Sound design is great.

Steventus has already said mostly what I think so I won't repeat it. But I want to emphasize his point on feedback to the player. For me that was the biggest issue. Sometimes destroying a turret would take two shots. Other times, it wouldn't die, no matter how much I shot. And honestly I have no idea why. It could be the bullet collision/ ray cast wasn't detected (a bug). It could be that the turret was armored from that side. Or was it invencible when the light was shining on them? If I had to bet I'd say it's the first option but I don't know, and I think that is the problem.

In any case, good job on your game! :)

This is a bit of a mixed bag but you've done some good things, let's start with the positives:

1) The core idea is very interesting and quite cool. Being able to rewind and create alternate selves to fight together creates interesting dynamics. This idea has great many potential to be expanded upon such as having a new enemy that can only be attacked from behind, so you use your alternate self to grab all the aggro and basically shoot behind the enemy with your real self. This rewind mechanic can also be used for light puzzle elements etc. I like it!

2) Good controls - not the best but they feel good. The jumping is a bit off and sometimes I get myself stuck/unable to jump up platforms when I think I have.

I think you're off towards a good direction but there were a few essential polish in order to make it shine:

1) No recoil on the pistol makes it a bit iffy. This is noted because I'm unsure of your game direction. If you're trying to take this game towards a high-adrenaline, all-out-guns-out game like DOOM, then by all means keep the lack of recoil for all out bonanzas. But at the current game direction, it feels off and would definitely benefit from recoil.

2) Needs more feedback to the player, I don't know where I'm getting shot from. I don't know if I'm doing damage to the turrets. I don't know if I'm almost dead because sometimes when focusing in on the action, I would just suddenly die and rewind automatically which takes me off a bit too drastically. 

Otherwise, pretty good game. If you plan on revisiting this, consider your game direction and develop accordingly - is it going to be a more slow-paced strategic shooter (now that's interesting), or a more fast-paced high-stakes shooter (like explosions everywhere).

Cheerios.

This game is pretty good!  The hologram effect on the past versions is great, same as the effects.  The shooting and platforming were kind of weird though.  For example you can't shoot the turrets from the front which is kind of weird, unless this is intentional.  If it's intentional I think it should be mentioned somewhere since I was there mashing the mouse and nothing happening until I turned around.  The saving is a cool idea, but I don't think it is needed for a short game like this.  The platforming was off at times as well, as sometimes you would land on an edge and not be able to jump, which made jumping on small platforms kind of tedious.  The gun should have a projectile that goes all the way to the enemy as sometimes I don't know what I'm hitting.  The boss at the end was cool, but the boss fight didn't feel "dynamic" enough, I could beat it standing behind a pillar.  However, it was a very good game!

I love the Alternate Timeline aproach allows me to use some stragity in how to take out the eniies by taking out mulltiple enimies at the same time this is awesome

Best Game I Played, Please Get To The 20 Rating mark, it was very fun, and amazing, I always try to find the bad stuff in jam games, so it could be improved on, but this is a masterpiece, more levels pleaaaase.. also, one thing that could be improved is maybe in the last level with the boss, he wasn't that hard, because of the wall blocking his shots, maybe make the wall a little thinner, that's it! Congrats on this work of art!

Wow, this was so much fun!
