yeah, having no visual change in the different barrels does make it hard to tell if they are implemented or not but doesn't mess with the gameplay if you only use the standard barrel.
Well level 4 is the last set of levels so it seemed like it would be for only the most skilled Lanky players but we are not that skilled so it was kind of frustrating. Thought that jumping had to be a part of it but couldn't take too much time trying to figure it out so just tried to see what the 3000 points door was hiding before the video was done but yeah..........couldn't do that.
Overall the game worked well, over time the player becomes more skilled controlling the hook making it a more enjoyable experience and it was just fun to play the game so still a great job on your more than a prototype but less than a finished game gamejam entry.
