This game is incredibly good, i have spent like 2h playing trying to optimise my train. Also art and music is amazing. I love to use of train whistle in songs. The only critisim I have is that sometimes if you get bad rng there is no way to pass second level, beacause all the upgrades could be for 30$ and there is nothing you can buy. Other than than, really good job. The best game in this jam I've played yet.
