Fun game!
Was going to say that the flashlight UI being a different size than the rest of the pixel art took away from the feel, but actually that was a result of weird rescaling due to me zooming in really far on the browser to play it fullscreen.
(not sure if it was supposed to rescale automatically but was very small for me)
Otherwise then, it was pretty solid all the way through!
Did have some issues with platforms moving down not allowing you to jump off of them, and I decided to climb past the exit to see if there was a secret in one of the stages, only for the screen scroll to kill me which...didn't feel great ^^; Would recommend locking the vertical scroll once it reaches the floor tile of the end door to avoid this issue.
The blocks which activate tiles were well made! I like how they have different expressions to indicate that they're starting to run out. Great attention to detail there.
The flashlight mechanics overall were fun, but could have made more use of it. There's a lot of horizontal movement potential you can do with the hover, but the stage design doesn't play into it much. From a combat point of view, I found myself without much reason to engage with enemies, and more incentive to ignore them and use the fuel to hover past. Maybe if you had some faster enemies that more aggressively chase the player, but get stunned by the flashlight, That way they're not so brutal that they can show up and kill you if you're low on battery because you could stun them get some distance while you charge and then finish them off.
Graphics were solid, and being checkpointed at the start of the level made it easy to redo things if needed.
Good game, would like to see it expanded on o/
