I eventually managed to win with Ratt Jr. in easy mode, scored 199600 points.
Normal might be doable for me with some tries if as I undestand the only thing it changes is that you only get one life bar instead of two but there are so many games that I'll switch to another one.
I had a lot of fun playing the game. The music is nice and engaging. I like the portraits, the art is consistent and the bullet patterns are easy to parse which is great as they're not trivial. The 3 boss fights are the meat of the game and they're all very good with notably cool patterns including the appropriate increases in difficulty between their phases. They're very satisfying to decipher, apprehend and beating the game is satisfying too.
I think the game is very good, thanks for sharing.
