Had a great time running around, exploring, saving moles, and beating up rocks. I made it to the second area (brown and sandy looking). I started to explore there and got stuck in a pit that I couldn't jump out of it... at that point it was GG for me :/
1. The aesthetics were great and gave a good sense of a big underground mole world.
2. The combat / punching was a bit awkward. Could've used some more audio-visual feedback ... but it was mechanically functional.
3. I wish the timer bombs had a more clear indication of when they were going to blow up. As it stand, you have some 3-4 second timer and just have to guess based on when you walked near it.
4. I want a map! It was very easy to get lost especially with all the same-looking terrain everywhere.
Overall, this was a great entry and a very ambitious one too. A 3D metroid-style platformer is no small task -- congrats!
