Hi YourBr0ther! Thank you for your feedback!
Indeed, the boss,when he is starting moving horizontally at least (second form) should have a sense of where the player is. In the current version the horizontal movements of the boss are random, that's why it can feel like he doesn't care about the player, haha :)!
The next version will have an improved AI with the boss going to look for the player when he is too far away (or too far away for too long). The normal enemies have detection ranges, one to go towards the player, that is pretty wide, and a small one where they will start to go in jump mode to annoy the player :). So i think these enemies are pretty much finished. Only the boss doesn't know where to go and what to do, it seems like he doesn't understand what he is doing there....yet! Haha :)!
Thanks again for the feedback.
