Oh you're right! I messed up the units. It started with m/s but it was way too fast for a snail so I ended up switching them to m/h but I forgot to change the multiplication factor.
Still, this was more like a proof of concept and I did this in one day so mistakes were going to be made. The game jam was three days but I spent two developing a game that ultimattely didn't work, and I had to make FTL Snail from scratch on Sunday. But yes, you're correct, I might fix the units when the voting is over, sorry for that, thanks for the feedback!
