New Features:
- Added the Chisel tool. The Chisel can be used to knock out corners from slope blocks. Left click will hit up to 4 blocks at the same time and will normally give smooth terrain. For more precise slope changes right click to change only 1 block. The Chisel only works on blocks which have an exposed top (so you can't use it to dig through walls) and will only re-shape a block (it won't remove blocks).
- Portal transitions are more seamless.
Fixes:
- Removed press "R" to toggle placing slopes.
- Fix memory not reducing as much as expected when moving around.
