There are some pretty cool ideas here, though the initial version I played seems only half realized.
I thought this was going to be a sort of twin stick and was confused when my attacks all fired in the same direction. I also found having to manually reload somewhat awkward. I did start getting used to it though, and I think with more distinct powers it would be more natural.
I liked the idea of having puzzle-like elements where you'd have to do certain actions to trigger dialogue with other magical girls, but there doesn't seem to actually be any of this in the game, at least not the parts I was able to play.
Some of the jumps in the area accessible from the door near the top seem impossible. I get that I'm supposed to wall jump onto the first platform, and I did eventually pull this off, but I couldn't figure out how to get onto the next platform.
Jumping just doesn't feel great in general, although it's hard to describe why. Wall sticking and wall jumping works pretty well, which is something that's hard to get right, but jumping in general feels too fast and too rigid.
The doors are too easy to hit accidentally and end up thrown back to a previous area... but they also only sometimes teleport you when you hit them. I think these should only activate with a button press, maybe with a prompt as well.
There's a narrative implied by the opening narration and the game page, but like the puzzles, it seems to not be in the game itself.
To be fair, I might have got stuck pretty early in the game and just never seen some of these things. There's no way for me to really tell as a player.
The art is minimalist and oldschool, but it's bright and colourful and visually appealing. I do wish there were more sound effects, and music.
The jam version is also pretty buggy. The first girl you can free gives you a flower card every time you talk to her, and one of my play sessions was ended when I died, teleported, and fell through the floor.
All in all it's a good start. I'll probably give the updated version a shot later to see what's been added.
