I really like the idea for this game, and the goofy vibes are very strong, especially with the duke-nukem style voice line at the start. I also adore the UI work, the little animation that plays when you first enter the bank is very well done and adds a lot to the tone of the game. The feeling of grabbing the loot was also very well done, and I like how there was some variety in them (and how you can kill people for it lol).
The movement is pretty good as well, and you really can't go wrong with a dash-jump and shotgun jumping. I will say that the low FOV made it difficult to get a good sense of my surroundings, especially when i go super speed with the dash. It also took me a while to realize that shift in air would do a slam, so that probably would have helped me earlier.
I would say the difficulty is a bit too high (could always be a skill issue of course lol), at least considering how much time you have to reach the end. There's an interesting aspect to how you have to decide how much time to give to each room before moving on with the heist, but I wasn't ever able to get a sense of this because I always died way before the timer even got close to being done. I think a lower difficulty combined with a shorter timer would let the heist part of the game shine more, since the player could do a few runs at first to start getting a sense of how quick they should go. At the moment, it seems like the difficult boomer shooter and heist game are at odds with each other, when I think they could work together to elevate them both.
The gunplay can also get a little frustrating since there is no indicator when you've gotten hit except for the number at the top silently stretching (amazing animation btw). A sound or screen effect would have helped a lot in letting me know if I got hit. It was a little bizarre that the gun doesn't aim straight at close range, but honestly I got used to this and it added a quirky charm to the game.
