The option to choose between stationary or movable robots and different weapon types are very interesting.
Sometimes I took the stationary ones and placed them near a work shop.
But I took often times just the movable robots because I wanted to collect all the money and had to move around.
I died sometimes because I got stuck between a horde of enemies or because I got stuck between my robots and the enemies. The second reason was indeed the most unforgiving death.
I also think it would be more enjoyable if the time slows a bit down or stops when you choose a weapon in the shop or if you want to change the behaivior of the robots. Because that's really the strategy part of the game and the rest is more reactive and giving the player enough time for their choice just feels more fair.
I played the game 4 times. But never beaten it. :P Maybe I will try it later again. 10 Minutes for one playthrough was a bit long for me. But that's just a players taste.
Anyway, very solid and polished entry! I would like to see a post jam version of this. :)
