This turns into a bullet game quite quickly I must say. I like the idea of self-imposing difficulty where you are basically your own doing. Making traps and turrets to make your life more misserable, even updates that worsen the situation, it felt quite nice doing so. Besides the gameplay, the art is nice, the upgrades are all meaningful and impactful, and it also runs smoothly with polish! Well done.
One thing I had to say is that there isn't much for the player to continue earning xp, and it felt like the difficulty was only for the sake of it, not any rewards down the line. I think players do need a goal to work towards or the game will fall short in the long run.
But besides that, this is quite a well-made game! Keep up the good work!
