I think the hitboxes are a little weird to get adjusted to but overall really enjoyable. Congrats on your game!

Fun game great concept!

fun but hard

nice game.  smooth gameplay with satisfying sounds, fun power ups, and inviting design and visuals. good work!

Pixel art is great and I like the instructiveness you put for the main title screen. Here is some feedback if you'd like!

• I noticed the UI button for the start is in front of the cursor art, it may be beneficial to change the priority or move the layers around.
• Some of the UI you used still has a little bilinear filtering on it, try setting this to point in the editor on your sprite and they should look a lot crispier
• Overall I think the gameplay loop is super nice, the enemies feel nice and combat feels natural. Maybe some more screen shake would be nice when being hit or hitting. 
• Smooth camera control would be good, if you aren't already Cinemachine is a great way to implement easily modular camera control that has smoothing applied so it feels a little smoother when following your player, it would be useful to look ahead of the player when moving and then return back to the center smoothly when you're standing still. 

Great work overall! Definitely a great use of the limitation and you implemented the theme well.

I like the aspect of literally feeding the timer. At first I didn't know what to do with batteries, but later I read the description and now I know.

I like it!

I started the git repo for this game; did nothing else; and it came out pretty sweet!

love this little game, the title explains it perfectly great work!
