Wow! thats a 5/5 in all categorys for me. I would straight up pay for this on steam because im a sucker for those types of games :D Theme is on point - controller feels nice - Visuals are really fitting the theme and the colors are chosen nicely (with the exeption of that one rock that looks almost exactly like the background :D) the upgrades feel rewarding and impactful and also have a nice pace to unlocking them... and of course the music is absolutely s l a p p i n g. :D Its very clear you are a rather experienced developer.
I got 211906 Core-Score on attempt 20 :D Thanks for Making and Uploading this! Awesome Job
