"bad colour scheme"? OK, if you buy games for the colours, this isn't for you. Otherwise....
This is a solid and fun group-style RPG, complete with turn-based battles that are VERY VERY reminiscent of Golden Sun. If you enjoyed that one, you will enjoy this, no question. Stop reading, go buy it, you will like it, I guarantee.
You control a main character who must try to track down what happened to his school teacher by stealing a rocketship and travelling from planet to planet, building up your powers through random battles, and finding friends to join your quest.
The graphics are quite cartoony, the dialogue is actually not too bad (humourous on purpose, rather than accidently, as one often finds with these import-translation jobs), and the gameplay is very familiar territory, right down to the over-the-left-side view of your troops against theirs in battle.
The graphics go right along with the general 'attitude' of this game, which is to not take itself all that seriously. This is pretty much the one distinction between this and, say, the Final Fantasy franchise. For example, the first King of the first planet you visit is named, get this, "King Gorgonzola de Fromaggia". The head cheese of cheeses, for those of you not familiar with Italian dairy products. Another example: you don't collect mana and healing potions, you gather yellow and green gummy worms, rubber boots and bandanas as armor.....you getting the picture? Yes, it is an RPG, in that you level up your characters through random battles, find stuff to buy and sell, etc. The only difference between this and Golden Sun is the fact that it is poking fun at the genre throughout the game. So, you won't exactly get completely immersed in the whole process, but it makes for an entertaining romp; sort of a Golden Sun meets Toejam and Earl.
I love it.
