I enjoyed the theme of your game. It's pretty cute and fun. I don't think my comments will be super different to the ones that have already been posted, but adding some more variety to the tracks would definitely boost the effectiveness of your OST a lot. As it stands, a lot of them really only have one section. Taking some time to develop the songs more and give them some contrasting sections would keep your ears from getting tired as the songs loop. Manipulating the basslines in each song would also do wonders as the lines do get drawn out too much. I do you think you have a good base to work off of though, and the overall soundtrack is pretty cohesive. 

I also wanna commend you for doing all your compositions in an online sequencer. It seems very limiting and it takes a lot of effort to push through those kinds of limitations. I don't know about your home setup at all, but if you can, I believe you can use Reaper for free forever *technically*, but nevertheless the license is very cheap if you wanted to invest. Pair that with endless free VSTs online and you can get a pretty good setup going for free/cheap, which would aid a lot in your compositional tools.  

Overall, you made some solid music in a short time frame though and that's a net positive for everyone. Thank you for the entry!

Just a couple pointers but I think you definitely need to focus on a couple things for next time. 1 being that you need to put a lot more variety into each track. 

Think about the OG Super Mario Bros theme. The whole theme is essentially about 1:14 but there are at least four parts (A theme, B Theme, C and D) to that one track. Especially with videogame music you don't want it to appear to be too repetitive because that music of course is going to have to loop a lot.

So just to keep it simple, while you want it to loop you'll want to have some variations (Add a beat, add another layer). Find some way to change it up to keep it interesting! Hope this helps for next time! :)

This comment is really gonna show my “Canadian who grew up in the early aughts”-iness but my initial reaction to your description was that the plot reminds me of a show that used to be on CBC called Being Erica, about a woman whose therapist basically sends her to these alternate realities where she can see how her actions would have affected her world and those around her. Anyway that’s a tangent so let me talk about ur music now!

I totally understand the desire to create a whole world for these jams (I’ve definitely been on the receiving end of the “develop the material you have instead of making more” critique!) but I think you could have cut back on the number of tracks to focus a bit more on some of the others. You have some really good material already, a bit more work into a few of them would have given you even better results. I notice your use of motifs from track to track, along with your orchestration, do give it a consistent feel! The cohesion between tracks is there, just a bit more focus on developing those motifs would have bumped this up to the next level!
