 Roguelite update:
   Technical improvements:
     Spawn tech: spawn every entity in a grid, before spawning check to see if grid position is clear, this will prevent any issues due to entities spawning inside one another
     Battle stats: DPS, damage taken, etc

+    This unit is a [class]
+  New stat system:
+    All stats are values from 1 to 10 (can be lower than 1 or higher than due to debuffs/buffs only) that represent consistent internal values between all units
+    i.e. 3 attack speed means the same internal attack rate value (like say 6 seconds) for the entire game
+    In general it's better if units don't have hidden internal multipliers on these stats, although sometimes that may be inevitable
