I'm not sure if I'm realistically going to have time to finish an entry, but the early Tomb Raider games were what got me started in game development, so I couldn't resist at least trying to work on something! I haven't really decided what direction I'm going to take this in yet (I'm torn between a 2d sidescroller with pixel art, a minimalist low poly more faithful recreation of the original gameplay, or a first person VR game adhering more to the theme than the gameplay), but here are some early mock ups and animation work that I've done this morning.
I've also made a very brief start on some music: https://soundcloud.com/neverreststudio/tomb-raider-jam-early-music-test/s-1hoFf
Fingers crossed I'll have some free time before the jam ends to get something more meaningful together!
