Recent verbatim reviews from Steam — separate from playze.io community reviews below.
In a word: Fantastic. For a number of reasons. 1) Simplicity, it's really easy to pick up and play and enjoyt 2) Challenging, it doesn't hold your hand and makes you work to progress and even if you are fully upgraded you can't just sit back and get a high score. It demands that you improve and when you do, you fell VERY accomplished. The different game modes means there's a LOT to explore. Wave mode is super fun and I'm excited to see how far I can get. I've played with the track editor and its super easy to use and you can make some awesome tracks to play to. I really appreciate a game that requires skill and doesn't let you pay your way around practicing and getting better. This is going to be a frequent flyer for me as I try to get better and better.
