The things that made me assume that it wasn't made during this Jam was:
- That you've uploaded the game twice on your profile, that's kind of red flags for me.
- That you have a whole 30 minutes of playtime.
- That it looks pretty great in terms of graphics.
If you made this game during the Jam, then I sincerely apologize for my harsh accusation. I just couldn't see myself making a game with this scope in a short Game Jam.
But you have to admit that it's kind of weird to upload the same game twice? But you're right, teams are definitely allowed! Good work!
