The NES inspired artstyle is cool even if I'm partial to other kinda artstyles, but like I said to another game, more styles and more expression is always great!
I also kinda liked (but maybe this is my own experience), how I discovered different mechanics as I went, first I realized the bandits gather northward to steal the money, then I realized that bomb timer around the screen was for the vault door to get blown open. I liked that the countdown timer didn't mean instant death. but was rather a change in game state
although, it did cause me to realize the best strategy is to just wait up there and shoot em when they gathered around. Still, it's a fun game, pretty simple, it reminds me of old flash games
