I enjoyed this game. It looks like a solid ground to make something bigger.
P.S.
- For some time I was confused about the control, as it feels inversed, that was before I figured out that I can rotate the character. Guess it would be better just to rotate the character 180 degrees on start.
- Character movement is to fast when you upgrade, it just does not feels right underwater.
- Some ambient music would add a lot to the vibe.
