Hi! Please let us build up a bit more between waves, as you cannot really think about a strategy if you're always overwhelmed by enemies.
There's no way to know if your base or your units are low on life, I wish there was a few health bars or something. Same, no way to prepare the next assault properly because there is no indication of the direction where the enemies will come.
Usually in this type of game you're able to know what type and number of enemies will come next, and from where.
The game itself feels like a good idea but sadly the execution is a bit off.
