The art, ambience, lighting, core gameplay, story and SE's are of top tier, thus making the game one of the most immersive in this Game Jam for me! I lost twice and played until wave 5!
It was a little difficulty to understand how everything worked at first, but once I did, I had genuine fun playing this. I think a tutorial wave visually explaining the mechanics would be really nice. As for the gameplay polishment, I found some issues, though I don't know if some of them are intended or not:
- Combat: Despite of having an attack animation when you click, the player apparently can't deal or receive damage.
- Difficulty: Game starts at a decent difficulty. However, after you build 2~3 towers, all you have to do is sit down and watch the monsters die. That's why I stopped in wave 5, because I assumed that I've beat the game.
- Economy: Magical Cores are expensive and very rare, while also being required in large quantities to build your main constructions. Sometimes the monsters drop lots of them, which is good, but normally they never drop it. I wonder if they have a low drop rate or if they should always drop them. If they are supposed to always drop it, then forget this issue.
- House (Immersion): When the monsters does reach the little girl, nothing happens. I think it would be a good ideia to place some barricades around the house (as a visual), because it's strange to see that the girl doesn't really care about the invasors.
- UI: some texts never disappears from the screen after you interact with them.
- Upgrades: I couldn't upgrade any building.
Don't let this list scare you. Your game feels really complete and has lots of features, that's why my full review is also long!
Overall, I think your game is one of the most potencial in this Game Jam: it's really fun, immersive and replayable and, despite of having a few issues, it deserves a very high rating in every category! Nice job!
