It really does feel like you have the start of something really interesting. Having to think carefully about the positioning of both your units and your enemies units is pretty stimulating, and even in this little demo level, I found myself actually having fun trying to set up hitting corpses or enemies into other enemies while trying to avoid falling into the same traps. The art style is simplistic, but fairly cute too.
This seems like a really cool direction to take, and I'm excited to see what kinds of mechanics you'll add onto this!
