I'm totally for a heist game, love the concept. Here are some pointers, some of them are personal preference:
- nice art! The only feedback i have is that sometimes visibility for important things as weapons arent 100% especially if there is a bunch of other things in the room
- I dont know what your design goal is but stealth isnt needed when you start out, it's quicker and easier to shoot enemies. I also didnt get the choke out mechanic 100%, it worked sometimes but sometimes it didnt.
- It felt a bit weird that enemies respawned when rentering rooms. In the same vein, placements in certain rooms (depending on where you entered) wasnt optimal, ended up right infront of cameras or next to enemies.
- Nice weapon variety, love the names.
- Very cool abilities, will be fun to play around with them in the future.
Good job!
