Make the stickman unable to jump through solid blocks. So if the stickman jumps up towards a block. The stickman just bounces back down. And maybe add an option to always show his health and display if his health is over 100 as a result of touching plant.

The stamp tool should be able to select by single pixels.

Some useful elements would be:
>Solar panel, like detector but only works with photons and absorbs them instead of letting them past. All other properties should mimic metal.
>A solid particle that behaves like insulation but can conduct heat outward when powered. But will not gain or lose heat from external sources (excluding heat and cool tool) when powered. When its not powered, it is the same as insulator.
>Allow stickman to use spark to spark any material where his head is. And while he has this ability he doesn't take damage from electricity excluding lightning strikes. Also allow him to operate devices that require p and n type silicon by pressing down while his head is near said materials. It would be a useful alternative to constantly erasing and replacing the two silicon types.
