This is a fun game, I like the risk-reward feature of rewinding a single run/risking the entire playthrough for more money. I also like how the bullets can collide each other, kinda cool, ngl.
A few minor complaints:
1) The triangle boss is so strong! Even with a legendary shotgun and grenades, I can't defeat the boss (it took so many shots!). I died and I gave up.
2) The grenades is not fun/easy to use and rarely goes where you want it to go.
3) Enemies can be sniped across the map without them reacting, making some encounters trivial.
But all in all, the core game is very fun and the time travel risk-reward is quite creative, good work!
