ah. i guess i missed that. i managed to play it and i want to say a couple of things:
at first it was nice, it became increasingly difficult over time and each time i failed and restarted i got more and more efficient with my time, however if you fuck up a tiny bit it costs a lot. i get that you have the emp for that but still. HOWEVER, and im guessing you know this but i figured out at one point you cant actually lose if you just focus on clearing enemies from 2 wagons instead of 3 since the third one being broken doesnt really do anything, im guessing you tried making the player want to save it by scaring him that his reload speed is falling but its actually not needed. so at that point the content of the game becomes stale since it stays the same practically forever. in general i would take inspiration from something like Dome Keeper to see how you could improve on this. but the base of the game is pretty nice.
Also a small thing about the cannon: at first it was a bit odd that i couldn't go 360 with the cannon and had to go all the way around to get from one bottom part to another.
regarding my starting experience that i couldn't find how to start the game: i feel like a simple outline on what can be interacted with would help with that, same thing with repairing health later on.
i also really liked the music, gave me original call of duty mw2 vibes haha.
overall i enjoyed it apart from my very first experience and whenever i solved how i can infinitely stay alive.
