Great game! I found buying robots and updating their settings a bit difficult with all the monster around me. Also, the monsters behavior could have some variation.
The monster warning screen (although pretty cool looking!) it should pause the game since there will be still monsters around me trying to get me.
Art is awesome, loved the animations in the title screen. Music was also on point (although mid game it paused an resumed randomly for me).
I managed to go as low as 50 seconds left in this great and polished game. Congrats! You should feel proud of this!
