I don't tend to be so harsh, but seeing everyone is downvoing I jump on the bandwagon. It's infuriating at first, with the upgrades it becomes... "playable" up until I was hitting like 5/6 perfect one shots and then it just became mind numbingly easy and repetitive.

Now the problem I had is that it wasn't fun at all. Or engaging. I think it was a fun technical challenge for the dev to make it but it's just not fun to play, I forced myself to play it for like 20 minutes only to unlock some upgrades to see where it was going, not because I was having fun.

Maybe there's an audience for these kind of frustrating games, but I'm not part of it. Sorry.

It would probably work as a mini game inside a larger game, but not as a game on its own.
