Nothing 'negative' at all, glad to read your opinion and comments :D
Yeah, I could play with the player mechanics and get simpler to put more importance on Teleportation, a good idea with the slime it's a good concept. For the Jam and in order of my skills I make super simple enemies and difficulty progression gets harder every 10 points.
I will work on smarter enemies, better enemies spawning, and a clear main goal ;)
Thanks for playing, it will improve :)
