Interesting* things I want to try out

• Learn about how to distribute haskell packages, deliver this game so it can run without ghc.
• Refactor using lenses.
• Pattern match on record fields directly. https://joshbohde.com/blog/pattern-matching-on-records-in-haskell/
• Refactor adding two-dimensional tuples with this: https://stackoverflow.com/questions/69422567/add-elements-of-two-tuples-in-haskell
• Refactor direction vector with Map
• Refactor zip with enumerate
• Learn about ghc profiling and profile commit 43336e2 against 0c4c428. These two are consecutive commits, but the latter seemed a lot slower in ghci, probably due to the huge refactoring of nested data types and excessive pattern matching.
• Anyway to suspend drawing thread during pause screen?
• Support more than 1 player mode
• multiplayer networking
