So far the project is good. I like the nods to Toys vs. Nightmares that the game has, by a LOT!!
I did find something interesting that not many has noticed, and it is the fact that the balloon does still do damage when half-inflated (I think around more than 10 starshots, but less than 13, but it makes its gimmick about clicking a lot more tolerable because most enemies aren't that tanky). That and that a fully inflated balloon has the same damage as the toy car (both of then can't oneshot a certain enemy at a certain moment)
Below here there are spoilers and my issues with the game!
And with that found fact, I do have to say that I agree with the game's main issue being RNG. Too dependant of RNG for difficulty. Especially with tricycles spawning early while there are enemies behind (I hate them, even if they can be countered by the teddy bears). It is so annoying to deal with and it is easy to lose because of that.
The other issue is that the boss felt underwhelming. I literally won against it with only balloons as damage, I didn't even needed to upgrade the music box.
... Not. even less than that. Just use the soldier and you don't even have to worry about the box, you can let it get destroyed and manage the soldiers (the boss gives in total 90 lights, so you can have up to 10 soldiers when its last phase starts)
My last issue is that there is not a thing that allows you to remove already placed toys, like what a shovel does to plants in the PvZ games. That would be actually helpful to remove not needed toys (such as teddy bears after a bird ambush). That would also make the toy car more useful because it really looks like it wants to be put behind for maximum efficiency. (Thanks for the keybinds to quickly put toys/upgrade the music box)
