I just finished playing through this. It was very rough, but I had a lot of fun with it! I noticed that this is marked as a prototype on the game page, so I guess the roughness makes sense.
I'm assuming the majority of the development time was spent on the art, because it is absolutely the highlight here. It's all very nice, and matches well. There are a few different styles on display but they all go together nicely. The character animations are a bit, but I think that was deliberate, and they're very smooth and natural. I appreciate the little details like Mina's ponytail and neck thing (yes, I don't know what that's called).
Although I did notice that some of the character portraits were cut off- was the dialogue system going to be a different style originally?
The gameplay is fun in general, and all the elements are there, but it needs some tweaking. This is kinda subjective, but it feels "sticky"- movement isn't fluid. It can also be hard to avoid taking damage in some cases.
But... there seems to be no incentive to transform. The minigun doesn't fire faster than I can fire the pistol by hammering the fire button, doesn't seem to do more damage, and can't be fired while crouching. I think this would work better if the minigun was considerably better than the pistol or there were other benefit to transforming.
There's also an easy degenerate strategy for defeating the boss but I'm not sure if I would count that as a positive or negative.
The story is witty, and I like where (I think) it's going, but playing through I feel like I'm missing context. A thin story is understandable if this is more of a prototype, but it's something to think about if you keep going with this.
The music and sound work well enough although it does feel like a bit of an afterthought. There's also a bug of sorts where enemies can kill you during conversations, and the conversations themselves are a bit clunky. Finally, I won't spoil the ending, but it really does feel like an "oh crap I'm out of time" thing.
Do you have any plans to develop this further? I think there's a really good game here.
