I don't normally comment on initial releases (I don't normally comment, period), and I don't know about any 'rendering', but this is a rather well put together game, for its current state.
Everything is smooth, the English is actually pretty good. I especially like the way some characters, like Bulma, for example, have animations during 'idle time' (eg, scenes where you need to click to proceed/go somewhere). Story is actually better than I expected. Kudos to the dev, especially if they can keep up this level of work.
Looking forward to seeing where this goes.
