I really quite enjoyed this. Zipping around the map through the use of explosions is really fun, especially since it doesn't seem to have a limit, so I can just zoom wherever I please. (That may or may not be intentional, but it's fun none the less) I like the kind of bounce the music has. It fits very well with a springy and zippy witch as they blast their way around the area. Controls were solid and felt reliable, though I think I would've liked a slightly higher jump as it seems be almost exactly 2 tiles high which can be a little precise. I thought the level design was pretty nice and well suited to the movability of the character. Tabitha looks great and stands out really well despite the sorta darker color scheme the game has and I thought the dialogue was pretty fun.
Unfortunately, my biggest downside will be the boss and the hit radius of the explosions. They're rather small, and coupled with small enemies, I sometimes find myself spamming to try and get a hit as they gotta be real close to register said hit. The boss itself is... two things. If I engage with it like how I imagine I'm supposed to, it's rather rough with the pits you can fall into being half of the room and the previously mentioned small enemies, but this ends up getting trumped by the second thing as I can sit on the far most left platform and just wait. The spawned in new ghosts won't chase me and I can just slowly chip away at the boss by being patient, which isn't all too engaging.
But all in all, great work! I really did enjoy my time with this game despite not finding the boss to be all that much.
