A smooth 3D first person shooter in GDevelop in just 9 days is seriously impressive — the movement controls feel really responsive and the retro art style gives it strong Quake and Doom vibes that work perfectly. The cube and moving platform puzzles add a nice variety beyond just shooting. The uneasy atmosphere the visuals create really pulls you in and keeps you exploring. Would love to see a health recovery mechanic and checkpoints added so the harder sections don't send you all the way back — great foundation for a full game! Feel free to check out my sky platformer too 😊
