* Took me a hot second to figure out that there was a flashlight meter and that using it all kills you lol. Like Thorrin said though I think it's a scaling issue for me that makes the bar too small. The game is super tiny on my monitor
* I thought the graphics were really nice, the tilesets reminded me of Metroid and the walk animation was cute
* I also like the flashlight mechanic, having a meter that you also use for hovering is rly cool. Killing enemies takes a long time though. But you really gotta take your time and think about what you wanna do I like that
* There is a bug in the collision esp on the ice level, there are a couple spots like this where you can't get through blocks you already destroyed. It doesn't happen every time but often enough you probably will have to start over b/c the only way around it is to hover way up and waste your flashlight bar (see gif)

Overall I thought it was fun and you had some good gameplay variety in there, great job!
