I think globally it looks good, but the "games" is too small (maybe need about 50% bigger
) ; also, the font used for Mana isn't "serious" enough ; I'm not sure how to explain, but I feel like it doesn't show what Mana Games is about. It'd be more in phase with casual games, for example.
For Mana Games logo, I'd like some kind of seriousness & mystery... I'm not sure my own logos really successfully achieved this goal, though...
The idea is that Mana Games should have a logo fitting the tennis games (which are the main games right now), but also RPG or Strategy games (maybe the future games someday
)... So it's kinda a stretch between the 2, and it's not too easy to achieve...
