When you play flash games, there are things that you probably appreciate; like sound effects, nice visuals, death animations, proper clipping, good music, story, score, different ship models to choose from, a sense of accomplishment from completion, incentive to keep playing, breaking bad references, originality, well thought out levels, long games, nicely drawn menus, games made by veteran developers, achievements, in depth tutorials, ranges of difficulty, challenging game play, glitch free game play, a fun game you want to share to other people, short lists, and fun.
I've got some bad news
P.S. clearly none of this is original, I'm just going through all the steps to make and publish my first game. any critique is welcomed. although you probably don't have enough space in the review text box to point out all the flaws.
