Took a little while to work out what was going on, but once I got the hang of it, quite fun. Would be good to have some sort of damage indicator for the baddies, so you know how much more you have to shoot them to kill them.

First prop for color blind accessibility options. Don't see that often and it deserves mentioning. I like the look of the turrets, they look hand drawn and like paper in a way. I hope that was intentional.

The first level was fun but second one had so many enemies with so much hp. I forgot I was even supposed to be moving around to collect things because it didn't seem like I even took damage. Not sure what the lose state is here. 

Great idea, however I think some things could have been changed to make it flow a little better, first off when I opened the game it asked me to buy a wagon and I didnt even know what the game was about, secondly I think the enemies are way to strong or the incentive to go towards the boxes is not that high, meaning I dont have a lot of money so enemies don't die. I had to stop after like the third buying round since the game was really laggy with like 400 enemies

The game looks clean but sadly unfinished, it has potential, I really like the train defense idea.
