This was great!
I loved the idea of finding bombs with the metal detector... it gave a common puzzle a very nice touch!
Everything was easy to understand through trial and error. Maybe game could use a bit of cooldown on weapon use -at first I was certain I needed to blast fires with 3 blasts at minimum for them to disperse! I learned how to use them properly fast enough, so its not a big of an issue overall.
Thanks for sharing :)
