While the execution is really well done, visuals are great, SFX are good, music is nice, and the idea is interesting, I have some difficulty having fun with the gameplay. I think it's too hard to get a perfect time, and if I get to 8:29 instead of 8:30, I'm cooked because it's impossible to adjust by just 1. Maybe some slower dice rolls could help with this.
Anyway, good job doing everything yourself!
