If I could give it a neutral rating, I would.
The game itself is not badly made, I just found it really boring and quite repetitive.
There's also this weird offset bug (only for wide monitors) that makes the upgrades hard to use.
The game itself is also quite short, which isn't necessarily isn't a bad thing if you like that (you can 100% it in a couple hours, probably less).
For the cheap price however, it's not terrible, but just not for me.
