Complaints:
1) The drag and drop things really needed a tutorial. I managed to figure it out on my own, but it really would've benefitted from some explanation.
2) I honestly thought the lack of music was really noticeable, and the sound effects on their own just didn't sit right with me. Some music would've made the overall atmosphere much better.
3) The gameplay seems just too simple for the level of difficulty. Like, once you get the second server, it becomes really hard to manage. especially once you hit four trees. Also, when you hit that 4th tree, I wish it would have some sort of popup text because I lost most of my runs just because I didn't know that 4th tree was there yet. Maybe rather than adding a 4th tree add a 4th level? Or even just being able to zoom out the camera would've helped a lot.
Compliments:
1) The art was really nice. I don't know what else to say on that.
2) This game was really well polished. For example, I really liked that the characters you get are randomized. So in one run you could start with the bird and in another you could start with the mouse, etc. Even though it's only aesthetic I still think it's a great touch. Just goes to show the level of polish this game has.
3) No bugs :)
Ideas:
1) Split the game into days. This would allow a sort of calm in between all the frantic serving and stuff, and also allow for more expansion of the game.
2) Different types of ropes could really help once the game starts getting more chaotic. For example, maybe have ropes that alternate destinations, since that could really help once you have many servers. Even just using that one new type of rope, I can already see many interesting ways to use it, such as using it to allow server to automatically patrol the entire area, allow you to focus on new things that might be introduced (I know that you probably don't want to player to be able to do that, but if you were to expand the game, there are a ton of different mechanics/changes you could add to balance it). Obviously I barely thought this through, since it is just a rough idea, but adding in more mechanics could make this game much more engaging and fun.
