Nice game! It feels pretty polished, the music, the start menu, the settings and the mechanics of the game. It is a simple but fun idea. Would be cool to add some backstory as well if you manage to find the time, maybe a cutscene at the beginning explaining things - how this character got into this situation. I think the perspective works well visually but I suspect it would play easier in 2D or a more directly top-down perspective as it was harder to judge angles etc with the current camera angle. Maybe you can make it so that if you push people off the platform you get negative points too :D (although I understand that gorey humour is not for everyone). There does seem to be a skill to the game, I had to do more careful flicks to get players in, managed 12 in my second run with two full trains, not sure if this is a good score or a bad one, but there definietly seems to be a knack to it.

The game is very engaging and dynamic, loved the idea! It's a bit too hard to hit the mark though, perhaps consider allowing the player to position the attendant anywhere?

The game idea is very neat but I wish the difficulty was lower at the start as I felt I had to be overly precise with my shots which sometimes felt frustrating, so maybe increase the train door opening size. I also really enjoyed the sound design when the passengers crash into each other and the music fits really well here.

This is actually a fun game to play! With more improvements I think this will be a great game. Try to make the train door bigger to give more leeway for the players and some bumpers at the back as a helper for players too.
