My first entry for this challenge is now up called Widow X Stunts!
https://infinity.disney.com/toybox/4c19a2db516a460581cd286e3f51b853Prove your skills as an agent of SHIELD, in this Motorcycle Stunts Arena designed by Black Widow! 1 Player. Leaderboard included!
Hope you enjoy it and that everything works well, let me know your score if you played. Not sure if the leaderboard is working or not yet. I managed 144 points so far.
I'm still working on a possible second entry with Big Hero 6 as theme, that one will have a bit of adventure feel to it, rather than just an arena.
