Hi Rona! Your idea sounds very interesting!
No worries! I am looking at assets that I bought from the asset store for Halloween. An insect/ humanoid pack from Maksim Bugrimov caught my eye (love his 3D models). What if humans changed into insects during a radiation apocalypse? You are a Mantis who has been caught by a humanoid ant colony and you are trying to escape. You use your own 'green' blood (health) to destroy the ant/ enemy. To replenish what you have lost you have to eat ant-eggs where ever you can find them.
I think I have laid out what I am going to make! [Great!]
