Well done on your game! I played through the entire game and overall it was an enjoyable little game that has much potential to scale.
A list of comments I have:
- I found the game very challenging, mostly due to controls
-I would've preferred to point where the ball should go instead of 'slingshotting' the bullet by dragging behind it
-Either the dragging should not require you to hit the bullet, or the hitboxes should be more generous, I struggled to get a hold of the bullet sometimes, esspecially since it is not on a fixed position on the screen
-The hitboxes of some of the objects were a bit punishing or a bit too lenient sometimes, this was especially noticeable on objects you scaled a lot
-The game would really benefit from having incentive to go fast, for example there could be destructable object you can only push through with a certain amount of speed. To aid that perhaps you should got for less tight corridors to promote more risk taking from the player
-The cooldown and limited usage of the slomo had no feedback, there should be some visual or auditory indicator (apart from the text!) to tell the player it is about to run out
-I have a widescreen monitor and some UI elements appeared (partially) off screen
Dont be fooled by the large number of comments, I did thoroughly enjoy your game, and the idea and concept behind the game is great. There's just a few (relatively minor) thing which I think could elevate your game from a good game to an amazing game next time!
