I wrote a really long comment, then I clicked post but it didn't post, I refreshed and now it's gone, so I'll just summarize what I wrote.
I can't vote on games because I failed to submit a game in time. The game was quite fun, especially the grapple mechanic. I accidentally clicked out of the game window a lot, this was the biggest flaw of the game for me.
As a game, it's pretty good. As a Lisp game, I'd say it fails due to being written in a fake Lisp (Fennel, just S-Expression-like syntax around Lua) with some parts just being plain Lua.
