I really love the concept. With only 8 bit art style and very little dialogue it really made me care for the rock, the knight and their friendship. Those little dialogues really gave a lot of soul to the game. The presentation is great, the game looks really beautiful. The music, while simple, is really nice, The controls on the other hand are a bit frustrating. Especially on laptop touch pad, where it is difficult to always double click accurately. It is better with a mouse, but it is still a bit annoying. The main drawbacks of the game are how long it takes to retry. Many times I would die at the last bit of the level. The other main drawback is that you often get stuck. When I lose in the game, I don't feel I want to retry and get better but rather that I have to do the whole level again to change the angle I shot the rock in a little bit and maybe now it will work. That makes it not too fun. Again, it's a great concept that has a lot of potential. Some suggetions for further developing the game would be to make the chain climbable, so he doesn't get stuck. To show the trajectory of the rock. And to have a life system. Each damage point can give a pretty big knock-back, to avoid damage throughing the levels. Just some ideas. Overall, it's pretty impressive you managed to do this in the 48 hours of the game jam, and would love to see it developed further.
