Thank you for the feedback. I truly appreciate it. This is how I improve, so don't be sorry. In a matter of fact I would love to hear more in the future.
I am working on the bug you mentioned. Regarding the graphics I feel that I reached a stage were I have graphics that are acceptable, and considering my budget and the fact that it's a self funded project, improving the graphics isn't a priority. However, improving the language level is, especially since English is not my first (or even second) language and language is very important in such project. I am planning to invest in some professional editing / proofreading.
