I just streamed this game co-op with a friend.
It’s a lot of fun!

It’s very well-made and the game mechanics are very well thought-out. The music is catchy and the pixel art is clear and easy to read. In co-op there are also good ways to help your fellow firefighter, whether it be by guarding the hose or a particular room, or by splitting up and having one player grab keys or hose extensions which the other player can immediately use to open doors or bring the hose in further.
It’s pretty impressive how the mechanics are so well done, especially with the limitations of NES game design. Highly recommend this game!
