Really good job !
It's pretty polished and It looks really nice.
They are a few things that could be improved though. I feel like having to spend all your movement points before doing an action is a bit annoying.
It's a bit hard to know who I'm targeting (but it's usually who I think I'm targetting so good job on that ! Just need to be a bit clearer visually).
Another little thing that might seem stupid but I feel like the doors should contrast more with the rest of the assets. I was ignoring them at first, forgetting doors where a thing :D
Anyways, very great job ! You have done an impressive work in 3 days ! They are a lot of things to be loved ! The game reminds a bit of Hotline Miami in its artstyle and the character design is really well done.
Great game !
