Interesting mix of genres and use of the theme, i also like the characters design and attitude !
Its also nice that you made a varied party with both ranged and melee characters, however i'm a bit confused by the combat with ranged characters cause it seemed that at times i couldn't really shoot and didn't understand why and i also didn't know what the enemies hp was :/
Other than that i feel the concept is solid and i like tha character switching and of course their snarky dialogue XD
1 week to make a game isn't much so taking that into account, even with the issues i mentioned what's there is nice regardless.
So good job :)
