hey! seems like a good start! (: played it until it dropped me to desktop, so i think i'm a winner winner... obviously a win screen would clarify, or at least a drop to title
controls seemed fine, though we need gamepad STAT! cuz i love me some gamepad, but plays fine on keyboard
i do like the use of the space key, felt intuitive and comfortable from WASD, but my silly brain didn't realize i needed another key at first, i think i would pickup 1 water and walk over 1 fire tile... the fire hose action wasn't obvious, but it is cool as it did more than i expected...
also i'm unclear how many units of water i pick up, the ability to put out fires lasted much longer than i expected, i thought picking up 1 water would be good for one chance at putting out one fire or at least one line of fires with the fire hose... if water is ammo, i guess i would like an ammo counter
i was confused by the cracked mud tiles, they added nice visual variety but i expected them to do something different from the green grass tiles, however, i never noticed anything... similarly, i picked up bombs but never tried them, so no idea about that
to get really petty, the third level or so seemed pointless, but maybe it was the mud tiles had a hidden purpose and i simply never experienced it
overall, game was cool! no wait, add sound effects! omg, it's such a silent game, but even if you don't add music (which i know you will, and i agree) the sound effects will instantly juice the game
hope this is helpful! keep it up, you're doing good work!
