Just fixed a few small things:

• Blocks now consume + require the amount of energy they say they do, instead of only costing 1 but refunding more than that.
• Small tweaks to the way block placement is handled, so things are slightly less fiddly (especially with the tall block)

Planning to update again soon with a liiiittle bit more:

• Free-build mode where you have all blocks unlocked and no shinies to collect
• A couple of extra blocks for free-build mode that should let you build slightly more interesting/fun things
