Yes, it looks a lot like Cave Story. It feels a lot like Cave Story. A LOT like Cave Story. But Cave Story this is not. From the boss fight and the characters' interactions, its a lot different than Cave Story. And before you tell me what I already know, The Underside was inspired by Cave Story, so much so that Pixel had commented on The Underside, somewhere along the lines, and apparently Pixel is not at all offended, if I am reading
this interview right.
All of that aside, Cave Story and The Underside, from what I can gather from the demo, is like Cave Story, it is a hard game. It could be said that it is harder. It took me about ten trys to get past the first (and only) boss provided in the demo. The jumps require a little bit more skill, I believe, than the first part of Cave Story. However, there is no massive onslaught of enemies, which seems to constitute most of Cave Story. Lets compare it this way. Cave Story is to Mega Man where The Underside is to Metroid. Which is exactly opposite of what he says in
this interview. But whatever.
Go try it out. The Underside is a fun game. It looks like he has a lot to do on the development - there is no way to change weapons, they seem to usurp the last weapon you had, even though you need them to progress. The characters and story are pretty engaging, like the mouse that steals your whatever it is in the beginning.
I am going to be watching this closely, and see how it pans out.

VERY much like Cave Story though.
I agree on all points. However, there are some big differences. But yes, the resemblance is there, and you can see the definite inspiration that is there.
