I like that you have to go rescuing slimes to be able to recover life and be stronger together, the only criticism (which is not serious) is that the square boss makes it easy for you to lose a life, if you remove the spikes with a turret and go where are you is life lost
This is our game in case you want to play it, feedback is very welcome!
