(Edited to put picture on bottom)
This is a great game for how early in development it is! A few things i suggest is possibly adding a sandbox where you can plan out how to place units, and adding something like a wizard with an AOE attack or a rouge that attacks quickly / applies poison. Also maybe add a snake enemy that moves quicker and a turtle that moves slower but has a lot of HP. overall really exited for any updates in the future!
I would go further but nothing gets past anyways. ¯\_(ツ)_/¯
