I bought the expansion as the main game had gotten to a pretty decent point, but wow, the game is a mess now. My favorite two new bugs/features are the Sierra-esque pixel hunting when disassembling and the absolute trash images when trying to buy/craft parts. The Hellcats engine has a "Piston A" and a "Piston B" with the images swapped. Some parts are oriented in a way that you will still question if its the correct part even though the name is correct.

Seriously, I expected better. I expected you to not release a buggy and half-♥♥♥♥♥♥ expansion like you did the main game, but it appears this was to high of hopes for you as developers.
