Very cool idea for a mechanic, and the game page looks great! I wasn't able to get past the boss at the end unfortunately, since it attacks are pretty fast and the player can't move while attacking

This is actually really nice! I normally do not say this, but the thumbnail did quite a disservice to the game, given how good the pixel art is in the game. The idea is really nice, shifting the age of the player character as a mechanic makes the game feel more like a puzzle platformer, and I am not complaining. The game comes with a boss fight too, which is a nice surprise.

Other things I like:

• Not really difficult yet not a-walk-in-the park level design
• Really great player character and enemy art
• Sound feels nice

Suggestions:

• I think the animation's cool-down after an attack makes the game feel really unresponsive after attacking. It makes combat not as enjoyable as it could be (And that's why I preferred the old man, as he has the least cool down). Consider halving that, and it would make a noticeable difference
• Boss attacks (and normal enemy attacks) are too fast to react to (paired with the above point), and it makes the boss fight quite unmanageable at times. I don't think it needs to be slowed down a lot. Just a bit would be enough
• I'll suggest having some more noticeable effects to show you are getting hit. This would make health management much easier
• Can we have W as the jump button too?

Anyway, this is a really surprisingly good entry. Well done!

I thought it was pretty fun and the art was nice. The one issue that I had was sometimes the double jump just did not work. But other than that, pretty good!

If you would like, please try out my game too!

Nice idea, forcing to play a different character mid-combat feels too sudden, maybe a big hitpause would help me adapt better with the change.

Very creative, love the idea of aging yourself up, and got very much Celeste vibes. Good job
