TY!!! And good luck with your project as well!
To be fair, that's more of a design choice than a technical issue. We discussed it later and came to term that a short ranged range attack could also work. Suffice to say that we're still testing everything. We've made an projectile template so it's easy to make other types of projectile upon it.
I personally love to nerd about physics in game, though currently there are other mechanics that still has to be made. Temporary upgrade is one of them and I can see a ballistic projectile reaching different height level being one potential upgrade.
Thanks again for your input!
