Some indication when the next wave is coming is definitely something I want to add.
Yeah, different enemies had different health and speed. Special abilities is a really good idea. I added the tower and fence buying stations to make the game more dynamic and have the player run around a lot (the same reason you have to restock the towers ... to make *less* towers *more* manageable ^^). Maybe I've went overboard with forcing the player running everywhere though.
There is actually an indicator on the tower (a bar that shrinks), but its not very obvious, probably also something to improve upon :)
I didn't get to do a lot of balancing, so in that area the game *really* lacks. If/when I revisit the game after the jam, thats something I need to put much more effort into.
Really glad you liked it :)

Yeah, I get the theme, that makes sense. I may have totally missed this, but was it possible to power-up one of your towers? I think the running around was fine, I liked it, I just didn't know when enemies would be coming and was kinda hesitant to even leave since I needed to restock my towers, haha.
I noticed the indicator on the tower after I lost a couple of times, and I think that indicator was fine, but maybe if the tower faded in and out (maybe a white color), or something to show it was empty could really catch the players attention.
Yeah, it was a game jam, so I get that balancing wasn't really a top priority, but yeah it was still fun :)
