Congrats on your submission, this is quite fun! The core mechanics are a good idea with the energy constraint + timer. The movements work but they feel a but "jumpy" or sensitive, which is a feel, but you could try slowing it down slightly perhaps? Idk. The artwork is a bit rudimentary but if you develop further, I do like the running animation where the legs turn into a circle it's quite funny and I haven't seen it before. Even in demo form you run out of energy too fast to get into the game imo, even extending it with upgrades (though ofc that's also the length of the level, so whatever). There's also no explanation for the objects you can choose from, for a new user this is a little confusing.
TLDR :The core concepts definitely work. if you focused on the artwork a bit, extended the energy count and added some basic audio effects (never underestimate the power of audio) this would be immediately fun.
