Bloons. With chickens. Is not something I thought I would saying or seeing in this jam. But it is freakin hilarious and a really fun game. I'm a big fan of tower defense and this actually sort of solves an issue with it that I've seen but not been the biggest fan of the fixes for, Which is the problem of endlessly increasing power mainly. Where eventually you just have this perfect defense setup and just leave it to go. Whereas with this each unit has a timer and so you have to plan around "Alright when will this one" disappear etc.
Although it's a little hidden sometimes which would be a nice change to make that a little more visible. As well as maybe a "3,2,1" countdown as to when they're disappearing, or something similar. Just to make it clearer when somethings disappearing. Though it wasn't too hard to play around them around disappearing as long as I wasn't messing a round obviously. Cause it was quite fun to just mess with the stuff.
Otherwise though I would say making the paths that foxes are coming down a little clearer than just a speech bubble would be a nice QoL, as well as maybe making it a little clearer as to where they're heading to. Possibly putting the coop behind a fence, that way it's just "they reached the fence" rather than "they entered the coop" cause it sort of seemed like they were aiming for entering the coop, which makes it look like essentially camping the entrance could work. But they don't, which means it does not.
One final thing that could add to some extra strategy would be maybe having some sort of risk vs reward to speed up tower generation. Could be, sacrifice an egg possibly or it could be use some sort of currency or another tower etc. just some way to strategize to make a little less up to luck, but in breaking luck you are sacrificing something essentially.
Besides that though the only real feedback I'd say is, I want more chickens, and more variety in what you can do with them could be interesting. maybe some sort of currency that you can use to extend their time and also upgrade them or something similar. Could be like an upgrade chicken sort of thing that you drop onto another chicken. Although there are the buff chickens so maybe not ? Maybe just an extender chicken etc.
