It's a fun little tool. I bought the premium version, and I've had a blast putting my game together, even though I knew squat about programming. However, there are a few things that desperately need to be fixed:
The game crashes if you enter a battle while in the Confused state.
There needs to be a way to publish games on other platforms, such as being able to make it downloadable on the App Store, Steam, personal websites, etc. Many people, such as myself, have invested hours upon hours working in their games, so there needs to be a way to at least play a game without using the RPG Creator app.
Battle dialogue needs to be able to be edited. For some reason, when I enter a battle in my play tests, the word "of" often appears next to nouns. For example, the battle dialogue will say "Aliceof attacks!" or "Received 50 Goldof!". At the very least, the "of" issue needs to be fixed.
The app is great for aspiring creators, but it does have some glaring issues that can easy be fixed by the developers. I hope you see this, developers: people are forking over $8 for your app. It's important that you fix the issues they're pointing out.
