Thanks for playing!
It's funny, basically everything you mentioned was on the board at one point or another:
The game itself is heavily inspired by the Insurance Fraud minigame from the Saints Row series, we had talked about making voice lines when flying in the air, and we had talked about different vehicles with extra bonuses - such as an ice cream truck that would "freeze" you upon impact.
Unfortunately, we didn't have time to implement everything, but if we ever decide to come back to this game and improve it, I'll make sure to pass along the ideas! And I'll insist on adding some kind of Batmobile because that just sounds too damn cool! :)
