Really good stuff! I love the massive number of mechanics that all come together by the end, and the puzzles are very well designed.
Only complaint is that the early game felt a little slow (I think there are some early puzzles that could be cut out without much issue)
Other than that very very solid and probably my personal favorite from the jam.
Visuals are iconic ngl, environments are really interesting to move around in.
I agree with Eric about the combat feeling a little bit slow, I want to run through these nondescript duck-infested offices leaving destruction in my wake.
Other than that there's just some polish things, like slightly higher fov, music mixed a little lower (it's so loud), and the elevator being disorientingly shiny.
Overall really good stuff!
It gives that warning for .exes too, pretty much any non-web game on here. Most people don't mind.
I know it is possible to run a jar file with an exe launcher of some kind (similar to Minecraft), but I don't know how complicated that is to implement.
I'll check the game out when it isn't an hour after midnight :P
Java applets aren't supported anymore in Chrome, and I think other browsers are following suit (NPAPI based plugins in general are being phased out.)
It looks like Itch does support it, though. Just keep in mind that the future of in-browser support for Java applets is sketchy, unless Oracle makes a native interpreter/whatever you call it for Java.
(Actually, if you are using Chrome that may explain the game not running, on my Chromebook at least it just shows nothing for the Java games on Itch.)
