v0.999990

This update has significant changes:

• The 8 levels for each mode are now pregenerated. When you die in Normal mode, you repeat the level. The current level set can be rerolled from the pause menu or by playing level 1 in that mode. Chunks no longer repeat across the 8 levels, difficulty is vastly improved, and your current seed for Normal mode is saved - allowing you to quit and try again later. The shots at altars remain random until I have enough types to reconsider.
• Altars now swap with your last shot if it isn't SAD (and if the shot offered isn't spicy / red). This was how it worked originally but I feared that people would accidentally swap back and misunderstand their use. I've solved this by requiring you to move 2 tiles away before you can swap again. Less risk and more utility.
• Now when you complete any mode the title screen changes - to give you a bit more satisfaction.
• Some background chunks were added, and a few adjustments to others.
• Many bugs have been fixed.

Prevailing roguelike dogma demanded that every attempt at a level should be unique. The objective is not to learn the level but the mechanics. This is still available in Hardcore where you would need my level of learning to thrive. But getting stuck on a boss, doing a difficult run back, and finally killing them with a build I could make with hindsight was far more satisfying than re-rolling the level.

I'm still quite happy with the randomised levels, but I underappreciated what it would be like to spend more time in them.
