Hi RetroPixelGames,
first of all, thanks for your purchase, I am happy you find this template interesting for you.
At the moment I don't have any planned update since I am very busy working on other projects.
I am however open for future updates. Once I receive many requests for the same features, I will see if I can include them with a next release.
About the dynamite and incoming projectiles, in the meantime, you could try to add it by yourself following the same technique used to enlarge approaching enemies. They would work similarly.
Is this your first time working with Construct 2?
Thank you again for your purchase :-)
