Hey! Art is beautiful. Really great design. The UI is fantastic. Really nice sound effects too!
What I would really want is some more level design, please put in buildings, rooms, areas, bosses. MAKE THIS A FULLY FLEDGED GAME because it looks beautiful, it sounds great, the shooting has good controls, it should just have level design and be fully fledged. No score nonsense (is it just trying to get a high score?), please make a full game with levels! (Then you can also make arcade high score setups that you can play on different maps, kind of like Dusk has because it looks really great and I like the start of it, I just want it to be a real complete game).
You don't have to take this into consideration, but I'm thinking of DOOM 1993 when I'm thinking of levels. Make complex areas, key hunting to open access to new places, mazes, and episodic levels to play through, with bosses at the end of each level. Please!
You could have a bit more polish on the player movement when you make it fully fledged, the water gun is really good though! I think it's sick. The UI is just amazing too.
One thing for the water gun mechanic, if the pump on the water gun could be a real interactable mechanic that you use your left mouse to hold (like a button on the pump) and then move up and down, that could be some great immersion, WHILE (don't remove) still being able to use the right mouse button for the water pumping too. I just wanted to be able to click and hold the pump up and down.
I think this game is pretty good. Just make it bigger.
