I hear you, this was my first game and l made the same mistake. I was convinced having a cool darkening and break effect on my biscuit sprites was everything, wasted 3 of my days just doing that as l haven't worked with shaders much, another 3 life got in the way. By the time l added the rest to make it a game, l couldn't include my sound effects, a tutorial or more than 3 powerups, all things people have mentioned for improvement. At least we've learned our lesson haha. Thanks for sharing though, as it seems much of this industry is pretty toxic tbh, especially fellow coders, so people sharing mistakes, and pushing their ego aside are refreshing.
