Hello there DragonExplosion! Firstly, thank you for trying out our game and making a video playthrough. Secondly, we love reading your comment. And lastly, we are glad for your interest and enthusiasm for our work.
We have plans for the enemies' mechanics and the boss battle. And to confirm what you wrote in your comment, yes, the enemies will actually chase you and try to kill you. But don't worry as you will be able to protect yourself somehow.
All of these will be added the next time we release something here. It might take a while since we are doing this project alongside our studies. However, rest assured that we will continue working on this and we hope that in the end, we are able to deliver the potential of this game. Once again, thank you very much for your appreciation and support! :)
