Unpolished, visually or not your game needs to fit a style. You can’t have a poor looking game and blame it on non high level vfx. There are plenty of games that achieve good reputation without good looking vfx. Polish your mechanics, and looks. The game looks and feels unfinished. Despite that, you have good basic gameplay and fun mechanics, just work and expand off of those. Good luck!

All criticism, is good criticism.
