There are a lot of games with this exact game loop pouring out right now, so I'm not sure how well it'll stand on its own without more unique mechanics (assuming the goal is a full release)-- but I have to say, this is one of the more polished ones I've seen! The UI is really smooth and reactive / enjoyable to interact with, & I really like the pixel art, especially upgrade screen guy and his animations. Once again very smooth and looks good. + The sound design, too.
Only thing I have to say about the UI, is that I would love for at least an option to disable to the controls tutorial on the upgrades screen, it it doesn't go away on it's own. It's not really necessary after you buy the first upgrade or two, and imo it makes the screen feel crowded. I feel as if removing that huge bar and positioning the Money count and Continue button elsewhere; such as a corner where it doesn't obscure prime line of sight for the upgrades you're intended to interact with, would be much less obtrusive.
(while I agree that it would be good to have an option to disable the CRT filter, it's not *that* bad, and people shouldn't be so aggressive about it. The way it's implemented here looks good imo, and I would keep it on, even if I understand why it may be a hard pass for some people. Just as an aside.)
I did not play very long, because I unfortunately feel this gameplay loop of hover-plusing to kill is heavily saturated, but this game does have some nice polish, visuals, and potential. I just wish it had gameplay equally as polished and a bit more unique / interesting, to go with the good visuals / UX / UI designs / plot (parody?) potential!
Also, I listened to the music while writing this review, and it's very fun. Again, I have to say, the overall artistic design is really good! I will definitely keep an eye on this game and see where it goes!
