Tons of fun but kinda feels impossible at a point.
Pros:
Visuals, while minimal, are very immersive and relaxing to the eyes.
Playstyle is straightforward and easy to understand.
Upgrades are a quick 1-6 keys that only appear when needed.
UI notification of incoming enemies is extremely useful and necessary.
I love the idea that the train is going around on a track. I don't know if it loops but it just feels amazing.
Game never lags and couldn't find any bugs.
Cons
Aiming feels awkward sometimes. I know the turret doesn't turn as fast as your mouse but still feels odd occasionally.
Fast firing turret damage maxes out too soon IMO.
Around wave 25 it feels like I'm literally incapable of doing enough damage fast enough to stop my enemies.
I gave it two runs but it gets repetitive at that point so doesn't have too much in terms of replayability.
Overall
Lots of fun and addictive! Hope to see more!
