I poked around and made a few rooms. This is fun! I love the live editing, it's cool to be able to draw some bits and immediately run around in them. I hit the tile solidity bug a few times which could be a bit frustrating, and it would be cool if the effects etc were discoverable, but this is really great for a first release!
thanks i'm glad you're enjoying the live edit. live edit is tremendously important to me. i think it's wonderful in terms of workflow and encouraging intuitition + spontaneity, so i knew from the beginning that this would have live options.
i'm sorry about those solidity bugs- sometimes if you switch tiles using the keyboard it messes up the solidity (i have a fix inbound for this). did you find the shift key? it lets you directly edit solidity.
i'm curious about your idea of making the effects discoverable-
how do you envision this working?
I don't have a really firm idea, but at least an icon on the palette instead of guessing based on blank squares would be nice. :) Maybe an animation when you hover the mouse cursor would be pretty self-explanatory?
