Games Like Curious Calvin

This 2D platform adventure takes place within treacherous tunnels deep underground. You play as Calvin, a brave, kind-hearted little creature driven by curiosity about the unknown world above. On your journey, you will encounter gentle souls in need of your help, as well as dangerous creatures looking for their next meal.

Survive the underground without harming the creatures living there. Use Calvin's shape-shifting abilities and energy powers to stay safe on your journey. While Calvin is fast in his green form, you will reach much higher when jumping while in red form, and you can swim and breathe underwater in his blue form. 

When exploring the tunnels, you gather energy for a run-speed increase, a protective shield, and a canon that only shoots tranquilizing bubbles. These abilities can be used when you need them to stay safe - or to move faster through the tunnels ahead.
