Really fun game mechanic and the creation of new robots looks super cool. The puzzles are neat and the game is very well polished. A possible improvement would be to add more functionality to the bullet absorbing shield or make a mini game out of absorbing bullets to make that part more fun, for example, if you shield can only be active for 0.5ms and has to be reloaded, you would have to time it. I loved the sound effects and visuals and hope that you continue working on this game :) Amazing entry and good luck in the jam!!
