Awesome game!
How deep do you want this to go? If at some point you decite to make it bigger or rework it a bit "might be needed if you create a bigger project, then I could see myself paying.
Seems like you need to fix the english here and there if even I notice that, but it looks like it has elements to it that could make it really good.
At the moment, I'm planning on doing 2-4 more chapters. Each chapter should be 1 or 2 hours long.I also need to correct the English; as you say, there are several errors.I'm saving money so that the "final" version of the project can be corrected by someone knowledgeable in the language. I also noticed some errors in the Spanish language. Thanks for the comment!.
