Very fun and simple game, the map I played was the backstreet Tokyo vibe.
I have always been a massive fan of TD games and this game has a lot of potential. Maybe there is a way multiplayer could be implemented and a way to skin the turrets through coins in game, no pay to win just creating value for playing the game.
I am sure the developer will be adding new turrets, the game currently has two turrets and they feel a little over powered as I was breezing through rounds after using the medium difficulty. This is more of a future fix as there needs to be more turrets added to help feel out what is balanced and not. Also you could add hints when a new round starts to help new players get a feel of how to destroy a specific type of capsule.
The capsules are very satisfying to kill and the sound effects to go with it, all well made. Maybe if you go down the route of customizing for skins and so on, maybe you could do an achievement or easter egg where you can unlock silly sounds to replace some of the turrets shooting or maybe add killing effects to give that players experience more personal.
Overall, 4 star game as I was able to play this for a few hours and for the state the game is currently in, very replay-able.
