Love the game!

Idea of combining an idle game with rythm genre really speaks to me. Although it would be cool if the clicking pattern changed from time to time. Graphics are gentle, which suits the music. In case of game design and fun - it is my favourite so far, in case of game jam theme - it doesn't feel very interdimensional...

It has potential for adding more content to it - including other genres than lofi would also be nice to see... and hear :)

A very cool game with a game jam that is not very suitable for the theme, but interesting gameplay and mechanics, we add another picture that is pleasant to the eye and it turns out just candy.

Idea
I really like your game! Although those 3 "Biomes" were in the same dimension, just in different places :) Still, the musical, environmental and instrumental changes made each "Biome" feel unique, and with a different atmosphere. Combining a clicker game with music and making a rhythm clicker is a really fun idea.

SFX/Music
Not much to say about that, really awesome. I like how you didn't get too much into a specific genre so that it's something for everybody, not somebody who just likes phunk or something x) My favorite soundtrack was in the last "Biome"

Graphics
As I said, your scenes have a really cool aesthetic.  Probably hand-drawn, the implemented "fake lighting" and little animations in the background and on the instruments made everything come to life! I also really liked the electricity fade effect on higher combo counts. The only thing which is not that great is the UI. The Transitions are cool, but what about a pause menu, with settings for the volume for music/SFX? Normally, it's not that important, but seeing as you have a music game, it could be useful ^^

Buggs/Improvements

• When you have 1000 coins, and you want to buy an instrument for 1000 coins, you cant. You apparently need at least 1001 coins to do that. Make a ">=" out of a ">" somewhere :)
• Too much text when you click. Instead of "Perfect" and under that "Combo 10", how about "Perfect x10"? Would make the whole screen a bit cleaner
• I'm not quite sure how it works, but combos don't really matter :D You just do it cause of the music. I don't think combos make you get more points, and if, they make you get more points with goods too. How about no points for fails, good gives you 1 point, and perfect combos give you 10 + your combo count, so for a Perfect x15 click, you would get 25 coins.
• Having the buy menu in a separate window is ok, but it was annoying when I didn't know how much the next instrument would cost, so I had to look it up quite a few times. Would be cooler to have the upgrades in the lower part of the screen, seeing as there is some empty space. This way, you could break combos when you miss a beat as well, and not let the players continue after shopping for instruments :D
• It would be cool if combos gave audible feedback, like the beat going faster/louder, or specific instruments getting higher/lower ...

Conclusion [9/10 Stars]
All in all, I think you guys created a pretty amazing game, in all aspects, visual, audible, and the code part probably was not so bad either x) It was fun to play through all the "Dimensions" and slowly build up the tunes, while also looking at the beautiful scenery :) 

Ok very interesting idea, I really like how you could turn on and off the different instruments to create different combo of music.

And the music from different dimension have different vibe which is really cool.

The graphics is also really nice!

Very cool game!
