Hi!
I can't say for others but I definitely am not prepared to share my e-mail address with filehosting.org in order to be able to tryout your game. Especially not because past filehosting.org reputation for hosting various questionable content.
So you might consider hosting your game elsewhere.
I guess requirement for entering valid e-mail address is probably just an attempt by filehosting.org to get rid of some questionable content but still I don't trust them.
