It's a great recreation of two classics, but honestly that twist with the dice is really well thought. It adds a dimension of risk-taking just to set your dice correctly to get a bigger score, and it's a really smart game design decision, because it gives a secondary objective to the player in a one-objective setting. Well thought!

This game certainly has good ideas and is too enjoyable. There are some point that can be polished. I'm missing the presence of sounds. The jumping cube game turns a bit repetitive once you master the timing of the spikes. The flappy bird game turns too hard in browsers (at least in mine), so maybe a different game mode or a biggest space to pass may be great.

The best way to innovate is finding links between distant ideas to create something new. Now it's time to rise the bets. As you have a pair of functional systems, try to add diversity to the experiences or a way to mix both of them. If you do it in a way you can maximize fun, the game can be really succesful!

Good job!

I like the idea of multiple game modes, both were simplistc but I found them enjoyable :) nice job!
