Amazing execution! Absolutely loved the reveal of the giant open world after the tutorial, very fun. Also enjoyed that you gave the player more agency than you would get in a typical game. I find that in game jams, it is better to let the player feel 'strong' or over powered, so giving the player lots of cogs to start made it feel very free and enjoyable.
Also, great idea to have a free roam mode after you complete the game, great feature.
Loved this!
