Hey Mike! Solid feedback! Glad you enjoyed the game. If you want to remove a chip you just need to find it on the right in the list, S0HN's starting 2 should be at the top. Then click the chip to have it highlighted in the UPGRID again and move or remove it. ^^
There is a good few QoL improvements that we can implement after the Jam. If we do I hope you drop by to check it out again!
