On rails shooter (literally) meets tower defense meets waifu. The gameplay is really fun, it's got a very addictive "grind" feel to it, which is not usually my thing but works here. Progression is very enjoyable, with tons of perks and accessories. It's like NIKKE but without in-app purchases, with a Senran Kagura type damage system eheh. Fanservice is nice but it'd be a good time waster even without it, which is my idea of a good fanservice game So far only three levels and a infinite mode. Devs are actively listening to feedback on discord, fixing bugs and promised new features, but even at this price point i feel like it was worth it.
