Fun idea!
A few suggestions:
- Let us use AWSD/Keys when in 2D mode. Clicking with a mouse is... awful.
- Let me have the movement happen faster. I understand every move the enemies gotta calculate a path to see where they go, but there are ways around this (a dumb way would be to pre-cache the possibilities of the next 2-3 moves)
- Add some sort of skill to the game instead of pure luck. Maybe an ability you can have to get out of bad situations, a re-roll of the dice, whatever it is.
Keep the great games coming, you did great!
