Collective review for:
CrazyMonkeyGames, 2D Play, AddictingGames, MuchGames, ArmorGames, BlitzGamer, DumpGames :
Either they are too busy to check their email for the past week (nearly 2 weeks for some) or they don't have the courtesy to reply when they don't want to sponsor.
GameGecko:
Seem reasonable, but will only sponsor games smaller than 1mb at the moment.
FlashPortal, Hallpass:
Willing to offer high and are very trustworthy but be prepared to only receive emails for a few hours a day, making the entire process take several days.
LegitGames:
Didn't reply to me for a week until I emailed again (since my friend got a response from them within 20 mins). Told me they didnt have enough money to sponsor games even though they were discussing a deal with my friend.
I've had a pretty lousy sponsor experience, its taken me 12 days from finishing and emailing loads of sponsors to actually get this game released. :(
