This game was wonderful, fantastic aesthetic. It was difficult and in some places it was frustrating moving screens and immediately walking into a fire. I also found that the octopus didn't give enough time to line up the shot and then fire, maybe instead of time you have 3 bullets?
The music was fantastic and for me it was the perfect volume, however it would be really good to have some accessibility settings to lower or raise the volume. Also consider that some colourblind people may not be able to see the different shades, perhaps it would be worth adding a blue and a red version so that everyone can find a colour scheme where they can see all the shades and nuance.
Really good game, just needs a few tweeks with stuff right in front of doors and doorways needing pixel perfect line up. Otherwise I loved this. Well done for making such a polished and complete game in such a short amount of time.
