Thank you!! I really appreciate that you take the time to give constructive feedback.And yes, it is very helpful.
The unintuitivness is the biggest problem in my game, since almost everybody gets stuck. I tried to make a the game that with just a few tries you could complete, but I didn't get it quite right. I think that's something that happens to many solo devs, who think their game is easy, but it's very hard for most of the people.
The restart points where something I really wanted to add, but didn't have time.
I agree with you with the thing of keeping the agent in sight. It was one of the first features I added, when I did't have a clear idea of what the game was going to be.
I thought about focusing the gameplay on pushing things, but I thought it would be boring, so made different, abstract things.
I'd like to make a full version with all this features and fixes that you alll put in the comments, I'm really thankful for these feedback!
It makes me glad that you liked the idea!!
