I played the demo of Aeon Drive quite a bit. The platforming physics is alright and the teleportation dagger mechanic was fun and felt pretty solid. The control scheme is garbage and can't be reconfigured which sucks, although that is planned to be added in the full version. It's generally a bit janky and unpolished but quite fun other than that -- I plan on getting the full version when it comes out, which will be in about a week.
Deltarune 2 was pretty awesome! It's got all the same good stuff from the first one. The battles are all interesting and creative for the most part, I'm liking where the story's going and the writing is generally quite great I think. I found Q5U4EX7YY2E9N to be really entertaining but I didn't like what they did with Noelle, I got pretty sick of her by the end. I might write a longer review at some point, maybe compare and contrast it with Everhood.
