This game is deceptively fun. When I first opened it, I played it for a bit, thought 'this is pretty fun' and closed it and was about to write a review. One of the things that I was going to mention was 'you should try to make big combos a little bit easier to achieve'. But then I had a realization on how to make big combos without changing anything, so I opened the game back up again, tried it out, and it worked. The satisfaction of hearing dozens of enemies die at the same time in a 50k point combo was incredibly satisfying. And what's more, even after I figured out how to consistently get crazy combos, the game still wasn't too easy. The only thing I can really suggest is to maybe add some more enemy types (shooters, etc.), and a bit more juice to a big combo. Screen shake, maybe a special sound for a big combo, maybe a combo meter that tells you how many enemies you killed with a single laser pulse... Dig even deeper into that ultra-satisfying feeling of a crazy combo.
