Something about the music and the tons of men running was just extremely hilarious to me. Great work on that front, haha!
That aside, this was pretty fun. My main complaint with the game is the lag during certain points of it, I guess this is caused by simulating so many entities all at the same time. Additionally, I think the game got a bit too hard a bit too fast. I only made it to level 5 before dying and lost most of my men in earlier stages. There were just so many projectiles being thrown around that it was very difficult to not lose men. Some of the turrets also seem to fire predictive shots, and even though they travel slowly it makes it quite hard to traverse safely! Other than that I think this game just needs a big coat of polish to make the gameplay really hit.
Overall, good work, and good luck in the jam! I do like the idea of navigating through a tower defense, it has the potential to create very interesting gameplay scenarios if explored further.
