The enemy stats were not randomized per se but their is some RNG. Their health is static and the rest for both player and enemy is based on D6 with a multiplier. So for instance the enemies have a multiplier of 2 for damage, then a random is rolled 1-6 and so their damage can be 2-12.
Thanks for the tip about canvases, it's something I want to learn to use just haven't gotten to it :)
