Fun little game. The controls are kind of undefined, and I coulnd't figure out what I was exactly trying to do after I reached 21.

I like the game and the pixel art style

I could play this on my phone for a long time.

Nice game. I wasn't sure what to do after hitting 21 though. After a few tries, I realized I needed to click the 21 (and go green) before it changed. After I figured that out, it was rather fun!

This is actually pretty fun! The only problem I see is that it is sometimes impossible to get to 21 (I got all 1's and 2's once). Other than that, good job.

Good work. Addictive stuff.

I got into a couple of situations where it was impossible to reach 21 though, because I started with only low values to select from.

Also it was a bit confusing at first that I had to click the number 21 once I've reached it. But I have to admit that it added to the gameplay and the stress that I had to tap it once I had the number right.

Took a couple of failures to figure it out. Very nice game!

I had fun with this :) It was paced well and pretty enjoyable

Kinda relaxing :-)
Some bleep chip sounds would have made it complete I think.

Neat little game! I could see this doing well as a casual polished version.

Really impressed by this game. It goes back and forth between high-speed reflex and suspense really well, creating a very interesting rhythm.

Nice execution of a simple concept. I found it surprisingly addictive.

Thanks so much for the feedback. Glad to see people are enjoying the game. I should have clarified that you need to click on the large number to submit your value but after a little bit of trial and error it looks like everyone figured it out. I'll continue to refine the game and clear up the instructions in the next version.

Yeah at the beginning it's not very clear how it works, but it's a good idea and well executed. I really got into it!

Your interface needs a lot of work! Took me forever to realize the countdown timer was the number I was adding to! Once I figured that out it was a neat little reaction game. Add sounds, polish and work on interface, perhaps?

Pretty cool. May lack a little juice - sounds, some movement, but then again the theme was minimalism, so I guess you decided to be careful. Starting a round with a "1" is quite a pain - instant loose :D

Interesting take on 21...

Very fun and addictive little game! I really like the simplicity of the mechanics.

Really nice and simple gameplay concept but definitely needs some sound to make it stand out more.

I liked the idea, although I wish there was a bit more on how the scoring actually worked. Should I hit 20 right away, or wait a few seconds so that I can hit 21 exactly?

Interesting. :)

Nice take on blackjack! I'm terrible at arithmetic, but apparently I'm better when I'm under pressure and don't have time to think about it. o_o
