Thank you for a thorough review, do you play on a wide screen? I noticed that the main menu buttons gets unaligned when when I connected to mine.
We had most of what you said as things to implement, different speeds and health on mobs. Mini bosses where nothing we discussed but it's a really good idea! Lack of time made the game unbalanced.
Thanks for playing and good luck with your own submission that I will go try out as soon as I have the time!
