Hey,
The game seems to be pretty fun but the only thing that is hindering is the looks of the game. The Game Graphics could be much better and the UI elements could be more appealing. Currently, the Font System which you are using is not that Impactful. Try to change the colours a bit while taking the Color Theory and Color Palette into consideration. The design also seems to be little off. You can first manage the looks of the game overall and then try out to blend the entire gameplay with the mechanics and all.
