Interesting premise & setting, but the gameplay is not that different with other match 3 games.
Consider this:
- Adding a power up/bomb if you can match 5 or more tile.
- Adding an attack item that when matched can be throwed to the monster/machine (to slow it down).

Nice & Simple

Nice little game to help polish your brain here.
The character art is complementing overall level style well, so I'm not complaining about it. I really hope there are more games like this in Newgrounds.
Btw, congrats for the release!
