I'm into lvlupscore.com this days, think Speedrun.com but for high scores not speedruns 

I want to do indie games but most are shmups and this get booring after many times any other games you can think of?

Something like the classic Donky Kong and Pac-Man games

It's a very short game, but Clawdia has a high score. You try to collect all the coins in the level, coins collected is your score.
