Introducing Mumm-Bott

Most of the last week has been spent on developing the systems for the first boss battle of the game/demo, the evil Mumm-Bott!


It feels like a pretty fun and challenging battle, which should be hard at first, but once you work out the pattern it follows it should be a lot more straightforward. He has fists that slam down on the ground to squash you and lasers he shoots from his eyes!


His head sprite looks a bit basic at the moment, and I’ll probably focus on tidying that up this week, as well as continue designing levels for the upcoming demo release. Stay tuned to twitter.com/gamesplusjames and twitch.tv/gamesplusjames for all the latest Portalnauts updates!
