This was a charming game to try out, the effect you achieved with the starry background looks awesome and the sprites look very nice as well. I’m not sure what exactly the enemies are supposed to be… but I like that about them, my imagination interprets them as inky metal birds. If I had to make any suggestions, perhaps an in-game popup to briefly explain the controls? Other than that the isometric world looks very good as well, inspires me to try making a game in that style at some point too. Nicely done!
