Ahahahahahah, really?!? The steam-punk mecha?
I mean, you chose a futuristic sci-fi theme for your game and you use the steam-punk mecha as a boss? Don't you feel that it is completely off-topic with your theme? :-3
If you had only the default RPG Maker MV resources to make your game, you could have at least used the SF_Machine to stay consistent with your theme. ;-3
