Wow! How clever! It is extremely satisfying setting up an efficient machine in short order, and then batting away all the fires. The premise, mechanics, and style are solid!
It was somewhat frustrating not having a quick restart option nor a level select.
Unfortunately, I couldn't make it to level 5. On my second attempt of level 4, the game threw up a memory error, and (without a level select) I don't have the patience to continue forward. I apologize.
All-in-all, fantastic! Great work!
