Hello!
I have tried your game. It was a bit difficult, but quite fun, well done!
I found some bugs, here's a full report of a few hours of gameplay I did: https://docs.google.com/spreadsheets/d/1ZGuxseUzf-MtSb5YcaQi8J39lDPh3_shb_SezeZK...
I also recorded my best run(no commentary), this might help you notice some things from a different perspective, here is the 27 min gameplay video: https://drive.google.com/file/d/1jw5WBXXERKTlY6jDaMVQ-wBr2zwUc5kl/view?usp=shari...
At the end of the video, when I lose, you can see that it skips the defeat screen, because I remapped fire key from left mouse click to spacebar, as it felt more natural to me. The spacebar clicks the "try again" button and immediately exits the defeat screen.
I hope this information helps you. Looking forward to playing this again later.
Best of luck!
Remi
