Congratulations on completing the game!
Some tips:
- port games to HTML format, people don’t like to download anything - in the browser you will get more players and reviews
- if you draw in pixel art, make sure that all the pixels on the screen are the same size, otherwise all the magic of pixel art is lost and it just looks like a low-resolution drawing, also try to never rotate objects drawn in pixel art - it’s better to draw frame-by-frame animation with them , where they rotate but still maintain a grid pixel structure.
- if you are making a highscore game, then try to make a gradual increase in the difficulty curve, in your case this could be accelerating the frequency of appearance of objects, increasing the number of these objects, etc. When the high score game goes on for a long time, it becomes boring, but this can be corrected by constantly increasing the challenge.
