Not a bad idea for a game. The controls are a little complicated, but overall the game is good)

Awesome game! It seems we had similar ideas, but executed them differently. The upgrade progression felt good, I was never far from another upgrade, which kept me going. I was a little confused at first about having to click the upgrade a second time to equip it, I thought just purchasing was enough but then wondered why my oxygen didn't seem to be going up. 

I loved that you had a final giant treasure at the end, shame there was no final purchase to trigger a game over! Some background music would have been nice as well. 

Overall very fun and well made game, great job.

Omg I loved the idea of the gameplay, I would like that the progression system was a little bit faster but anyways good job!!

I like the anvil lol

Very well done game

Have you played the old flash game Into Space?

This was really fun, great job! It reminded me of learn to fly :)
