Little buggy and slow, needs more
The fireball dispenser never worked for me, and there needs to be a way to adjust the game speed. Also, some sort of enemy guide or indications of immunity (stupid squid things are immune to water and lava, it looks like) for people who don't actually play Minecraft. Since this is kind of a niche game, that's a low priority but it would still be nice. I would love to see more upgrades and a way to regain lost health, maybe one every 10-15 waves. A little more variety on the trap and turret tiles would be nice, but might be hard to do considering the limited scope of the game you're basing this on.
