I played to completion. When I finished the game there was a bland blue screen and not even an option to quit to desktop.
The art could use some reworking, the level design as well - second level is too easy and the last level tricks the player because it feels like the enemies are going to appear from the bottom lane but they never do.
Thousand dollar turret is way overpowered. All you need is one and the game instantly becomes boring. After I placed one I found myself just browsing my phone because there was nothing else to do in the game.
I think saying the dogs are mini planets to fit the theme is a bit of a stretch, but I can see the thought behind it.
Game managed to keep me playing for a few minutes, that's rare for a game jam game.
