Once the lag died down, this game was pleasant. While the core game idea was solid, I do think that the odd way the shops' UI doesn't close and the lack of visual feedback on the train's guns do take it down a peg. I found the game really easy, but in a more zen kind of way (despite all the bombs). The calm music and tropical local actually made it pretty relaxing as I made it all the way to level 45. Nice work!
