Thanks man! I really appreciate your thoughts on the game and I will definitely consider them in the upcoming iterations. I plan to update some of the assets, either replacing them or touching them up. As the creator of the game, I know every mm of it and know exactly what you are referring to

Fair point on the difficulty, it takes a bit of practice to get the hang of it. I'm looking into the best solution for this.. maybe an intro level where it teaches you all the mechanics of the game in a light manner but still keeping it snappy (boom, you're in the game). And that is the point, I got to appreciate so much more the effort that goes into making games. Too much hand holding and the sense of achievement and discovery is lost, to little and people may give up. Finding the balance, that's the magic right there!
Yes, the art style definitely needs to be consistent ( even if it is a font), I will change the HUD a bit, but still keep it minimalistic.
Really glad you like the art style, I plan to make a siganutre part of my games/apps.
When the major update is done, I will annouce it here. Just know that you influenced the game a bit with your suggestions

Thanks a bunch,
Ivan
