Thanks for the advice. For the answer for 'large team' we are actually 5 first years that wants to gain more experience on team game design. And for the confusions of different tools, we wanted to do something like Escape from Tarkov styled game play that includes a currency system, store system and maybe an upgrades system and the accelerator is actually originally for the store system but unfortunately in the end we don't have enough time to polish the game. As for why we used AI, all 5 of us are just like programmers and none of us are professional artists, only one guy that drew the health bar and the eye UI have learnt drawing before, and he is working hard but the efficiency isn't still enough for us to complete all the UI and backgrounds before the jam ends. So to save time for the programmers and I've checked the rules and it never said that we can't use AI so I said 'Why don't we gave a try and we focus solely on programming, cuz we are still stucking on how to write AI'
