Thank you for your helpful feedback! I'm sorry to hear that it wasn't fun for you.
To answer your question, my thought process was that it felt satisfying when I was struggling for my life, slowing down and still managed to safe myself by recharging the battery and eventually pick myself back up again.
You're right that the main gameplay consists of avoiding the other robots, you can't influence the combat otherwise. Next time, I will try to make it more clear to the player and make it feel more rewarding. Maybe by giving the points more purpose and allowing the player to purchase upgrades with them, which had been my initial plan. Once they hit you, you can then decide whether to run away, or continue fighting them so you will lose even more battery but also gain some points for killing them.
I'm glad to hear you found some charming aspects in the game that you liked, it's nice that you gave it a chance anyway! :]
