Nicely implemented strategy game! It reminds me a lot of some other game I played ages ago, but I can’t put my finger on it.
The base implementation is solid, I’d just love some more variety on top like the buildings having actual differences, like the tower shooting stuff or a way to recruit new warriors or have archers.
It’s very possible that the shop already supports this or there is a hidden UI for these things, but I quickly fell into a cycle of surviving a night -> spending all money on the lost buildings -> repeat, which left me without any money to play around with in the shop. Except once where I tried to buy a sword, but it didn’t let me? Maybe I needed the blacksmith first? A bit more in-game UI and guidance would be good, I guess :)
Anyways, what I was able to play was very competently implemented, so good job!
