Hey I just finished my 2nd full solo game, it's made in unity and it's a 3D puzzle platformer game involving time travel. The game mostly involves platform puzzles, jumping on buttons to solve logic puzzles and open doors, and going back in time to create duplicates of yourself. You must reach the goal in 60 seconds, not including time travelling, and you can't collide with any of your past selves or you could cause a tome paradox that could wipe out thee whole universe! No pressure, have fun!
