short but fun, my most complicated looking bot was one that i could have it crouch or fire 2 repeating rifles, took a while to figure that out, almost didn't fit
looking forward to more levels, and possibly more weapons, bots and pipes.
for your first game, its not bad, since it actually completely functions unlike some games i have seen
you might want to add a title screen tho with controls, cuz at first i didnt even realize i was playing until i died, and didnt know what i was even supposed to be doing until i readthe instructions on the site, idk, maybe that was just me
