Hii, I've made a video about the game and wanted to share some feedback about it ^^, hopefuly it is useful to you :D
-The main elements of doom are quite well preserved here, awesome job.-Visually the game manages to be pretty readable while moving and overall I'll say that I've seen some tricks with illumination that considering the engine you are using are pretty unique and interesting ^^
-Controls could be a little bit more polished since making small adjustments while aiming was quite hard.
In conclusion, the execution is great and I hope you keep working on more PICO versions of different games ^^. Hopefully this is useful to you :D, also if you could subscribe that would help me a lot :)
Regards
