0.3.3: Bugfixes, Gameplay balance

This small update fix some concerning bugs and bring some gameplay balance with the goal of providing a less frustrating experience on a couple points. It should also make the pace of the demo a bit faster.

There will be less frequent updates going forward (except for major issues) so I can focus on making efficient progress on new exciting gameplay features.
Thanks for your abundant feedback that I keep reading every day!
