Hey Anisakia, thanks for the game!
This is a great game for those who enjoy those 'incremental' style games- it builds intensity as you progress, and is not exactly simple and easy (it creates challenges for the player.) This also has a original story that I find captivating- a real attention-grabber. It's also very playable even though it can prove to be a challenge at times.
Nonetheless, I did have a couple minor issues. One issue is the appearance of the level; we can see the outlines of the rock formation shapes, for example. Another issue is the left and right arrow keys- each time you press them it pops up a message 'reminder' about how you can not use these keys, this blocks whatever is in front of you and can make it difficult to see the mines and other obstacles. You get used to this, but still it's not ideal for playing. However, even with these things considered, I still believe that it is playable and enjoyable.
If I were to suggest something different, I would advise you to carefully review the game to see if you notice anything from an aesthetic point (such as those outlines on the rock formation shapes.) I would also advise you to remove that reminder and emphasize it in the instructions rather than the game.
Overall, I would give this 4 stars for having given me (and hopefully other players) an enjoyable game that can/benefit from just a few minor improvements.
Good luck to you on your next few games!
