Okay, the game felt a bit too random for me. Playing it feels a lot like clicking desperately everywhere in hope of having good results. Even with some strategies available, there's a lot of time praying the RNG gods.
But now that's being said, I must say that the idea and execution are still excellent! The core concept is pretty interesting, a mix between tower defense and clicker where we must try to improve the defense of each columns. As being said there's some strategies that can be found, and it's satisfying when they work out. Plus, the variety of power-up is impressive, and they all are super useful and interesting to play with! I had several games, and each time I discovered new way to play thanks to the bonuses I bought. It's pretty cool.
In the end the game might get too intense too soon. I really had fun once I had 3 or 4 power-ups, but the second wave is already really hard. Most of the time I didn't have much time to think long-term, there was always an emergency for a particular ghost. Which put me back on the loop "click until you get lucky". Which is also interesting in term of pacing, but there might be a better balance that can be found.
Overall, super cool concept, great and fun upgrades, just need a bit of balancing to make it feel less random or punitive.
