Hi. Thanks for trying the game and leaving a comment. Others have noticed the lack of shields. I think I might add some shields or armor after the game jam is over to avoid the one-hit kill.
Note: Dodging is easiest in form 1, harder in form 2, and hardest in form 3. Currently, the easiest way to play the game is to use all of the defensive capabilities with the TACTICAL (form 1) transformation early on. After whittling down the enemy missile launchers with this technique, you can swap to other forms to use your weapons as well.
