lmao I saw the arrow pointing right and just kept running in that direction for a full minute before giving up to restart the game thinking it was bugged, realised the second time it was actually pointing at the thing to move on.
For some reason, the second boss guy disappeared on my screen for a few seconds, then appeared again as I died on one of my playthroughs.
I'm not very good at this genre but I found it even more difficult than usual to move out of the projectiles trajectory and I cannot pinpoint why.
I think the rewind mechanic would have served better if it was a shorter duration and the bosses health didn't revive as well otherwise it starts to feel like a slower version of respawning with a new life, or at least let me decide when the rewind stops as this gives the user some interesting decisions on whether to save the rewind for if things go completely pete tong or use it just to top their hp back up after a hit or two.
The game got a little easier for me once it gave me a sniper rifle, I liked this implementation of varying weapons as it kept things fresh and interesting.
Overall its a good game.
