Heya, glad you like the art and music! :D
And honestly, I had some different ideas when first seeing the themes but seeing the optional themes revolving around music, part of me felt like making a rhythm game. (First time making one and I too am not such a good rhythm game player myself. XP)
Currently, for the jam build I submitted, all 3 songs are not playable. (Though I do have a fix already made in my current code.) In my rush to submit the game on time, I completely forgot to set back the proper songs + levels. ^_^"
And YES, I would be continuing to develop this game. (Currently trying to figure out some cool effects + some additional game mechanics, plus tweaking some of the timing + current code.)
Note: Also, I would love to go back and completely overhaul the "Plague Princess" game I released from MGGJ8, I've improved a bit and I know how to make it much better now! >:D
+ And that is a good idea, I'll add that audio cue to help with player feedback!
I'll keep the Discord channel updated, once I have it in the spot that I would like it to be. ;P
Thanks for playing!
