long story short this is a tool for sharing your photos on the workshop great in general but a lot needs to be done . played the game this things should be added : 1- a main menu 2- a menu for the workshop (i dont want to finish a puzzle to get to the workshop menu) 3- performance is on trash bin son ... 9 fps???? on a puzzle game ? optimize the code 4- you need a setting menu 5- i want to be able to change the resolution but i cant (fix this problem) 6-uploading works on workshop is way to complicated make it easy i want to be able to upload the photo or gif just by one click and ( choose my file hit upload and done. ) 7-you need new icons for menu 8- remove that unity logo if you have the money to buy the software 9- add new category for the workshop (gifs- anime related - irl - irl gifs - game related - game realated gifs )
