After working with Unity and trying to implement the core features of the game project I am working on, I have to change my previous statement that Unity is comfortable and easy to work with to an extend.
When I first imported the graphics provided by our artist he noticed that they looked rather bland and there were some lines that he was sure were not in the original files. The files were Photoshop CS 2 files and the importer inside Unity had some problems with them. After some tweaking the colours could be corrected but not the lines, maybe there is an image format that we could use that is imported correctly into Unity but as we are not working with the final graphics too much tweaking would be just a waste of time.
Another aspect of Unity that bugs me a lot is the movement of objects by script. Simple movement in one axis posses no threat at all and is easily implemented but creating a jump, that looks good in 2D and is at the same time "physics confirm" meaning it feels right in the given environment, seemed almost impossible at first and without using a set of external scripts. These scripts are included as a standard package with Unity but I wanted to avoid using scripts that provide functionality that is not needed for the project. Unfortunately it was only possible to achieve a suitable jump movement by using said scripts and add my movement scripts on top of them.
As a conclusion I was to hasty to praise Unity as I did but I learned a lot in the process and will test more before jumping on someone's "band wagon" in the future.
