I got this game in my queue and am very surprised about how good it is. One problem I had is that I didn´t really know what was my goal or how to reach it and I thought I was doing everything wrong, until I suddenly got to ur message XD.
If you wanna work on it in order to release it someday, be aware that indie game dev can take multiple years and make sure that this is really the one idea you wanna pursue, otherwise you´ll probably quit developpment a few months in...
But I think this has potential, especially if you add some more mechanics (incrementally) and explain the objective a bit better to the player.
