great game in the works, with some more features I think it has potential...
with the version I played, here are some of my critiques/ suggestions:
- increase the time
- some sort of risk vs reward mechanic (currency?)
- maybe the placement of your tiles can influence gameplay
- games that solely rely on your timing can feel a little too linear at times
the version I played was a little buggy but I think you fixed it since then. Great work either way and awesome game jam submission!
