The combat mechanism is something new, or at least for me, I like it. As several times already mentioned the player should be forced to leave the middle room, for example when staying in a room for too long a more dangerous creature appears, or if you still have motivation you could implement these powerups you spoke of.

The door is hard to access in the hurry, but maybe that's just me :)

The music sounds nice, but it fits to the sleeping girl, not to the dangerous situation of the incoming blob invasion :)

Great game anyways, keep up the great work!

The theme of the game is cool, and the combat and repair mechanics are refreshingly different :) The art is solid and fits the theme.

I think the game could gain a lot from a bit more variety, either by adding different enemies, or more options to combat the blobs.

As some already said, all I did was staying inside kelly's room (except when the enemies first appeared), poor Kelly, alone in a house this big and empty :'(

The sword's playing idea is great, that would be even better if we could push enemies around instead of just stopping them.

I liked the graphics, blobs are cute (nice intro too !)

The rooms mostly seem big and empty (even Kelly's). The blobs seem to come evenly from all directions, so it seems unwise to leave kelly's room, or at least to go far away from it, after the first blobs reach kelly's room. Getting attacked by the blobs in every room except kelly's further reinforces this. 

Also, every thing looks rather featureless: all the rooms look the same (kelly's room is only distinguished by having kelly in it) and the blobs look all alike. this is very boring.

Reducing the game to only kelly's room would be the best thing to do in my opinion. The extra rooms hardly add any value, and taking them out would pull all the details that are there closer together and highlight them.

I loved the general idea of the game, and the mouse as a weapon and transportation control was great, the graphics were good, I consider there is room for improvement in that area, like spicying the rooms or distinguishing enemies for example, also the music was a little low, compared to sounds but that's not a big deal.

Overall I really enjoyed it, and for a jam it's a great game!
