Also, I just took a look at the new version of the manual, and it is fantastic. Excellent job. However, the title of section 4.2 is not capitalized, with no apparent reason for being so. If you update the manual later, you might want to fix that. I'll keep reading through it and looking for other errors; even the best writers make mistakes and need a proofreader now and again.
EDIT:
In the list of features in section 1.1 is written:
Quotecustomize it however you want which is made as easy as possible because of the professional documentation provided
You might want to consider re-writing that as:
Quoteextensive customization options, made easy due to the professional documentation provided
EDIT 2:
Something else you might want to change can be found in section 1.3, in the version history. In the list of changes for version 2.8, you say:
QuoteBugs related to the combo system from 2.79 fixed, combo system now complete.
This is in a different tense then other changes listed. To correct this, you should change it to:
QuoteBugs related to the combo system from 2.79 fixed, completing the combo system.
OR
QuoteBugs related to the combo system from 2.79 fixed; combo system completed.
EDIT 3 (Sick of me yet?):
In the list of changes for version 2.7 is written:
QuoteChanged the way how spritesets need to be named for Actor Weapon Sprites.
This is grammatically incorrect and should be:
QuoteChanged the way spritesets need to be named for Actor Weapon Sprites.
This also applies to the statement above it regarding projectile spritesets.
Sorry; you never really asked for help, but I figured I'd give some. Feel free to disregard it if you feel it irrelevant.
