My review of this game:
Strengths:
The concept and art is very cool. The designs for (most of) the enemies are very spooky and I love how everything is animated. The designs for the towers are also excellent. The theming is very strong here, and I'm all for it.
In general it's easy to understand what each tower does without having to have the game spell it out for you.
It's also easy to understand what most of the enemies do as well.
Some things I noticed that could do with being changed or improved:
Holding on the music box is not the best. My finger got a little tired while playing, which wasn't an issue since the game was pretty short, but if the game was longer I would get very annoyed. Perhaps the music box could go automatically, and only stop in particular situations (like placing a tower)? I have the same issue with the balloon, where clicking it a bunch made me not a big fan of using it. Of the towers, I used this one the least.
The toy soldier wasn't much worth the investment. The damage is about the same as a star(?) and I don't want to micromanage their targeting. Either their damage has to be increased or they should target the front most enemy automatically. Otherwise the only real use I had for it was during the final boss.
The enemies were fine for the most part. I had a situation where 3 heads spawned at the beginning of the level. That sucked. The Ballerina enemy, I had no clue what she did. She made the enemies blue, but it seemed like they stayed the exact same in each way? Otherwise the enemies are generally decipherable.
I feel like the eagles were a bit out of place. Everything else is a monster or evil toy, but the eagle is just, an animal?
If I could suggest something though, maybe each enemy could drop 1 spark each? Otherwise by the end I am so rich that I can afford to lose many towers.
The cutscenes could be a little shorter, they seem like they are 30s, but nothing happens for that whole 30s.
If this was longer, I'd like for the game to be streamlined. But in general I very much enjoyed the game. It wasn't too hard, and I like the concept a ton.
