Got to the second level, and this game is pretty nice. One thing that stood out to me was the part where you choose a tool to be thrown away in exchange for upgrading another; it makes tackling the levels a lot more interesting if you replay the game.
I do have two small criticisms, however: The first is that selecting the tools with the keyboard numbers is quite annoying, and it would be nice to see an option for mouse-wheel scrolling (also on the topic of tools, I don't like how the icon for the tool you have equipped disappears from the screen. It would be nice to have a different colour to represent it instead).
The other problem is with the bloom in the latter half of the second level; it makes the white tools hard to see and is generally just an eyesore. Maybe it could be fixed with a bloom slider and a black outline for the tools.
I did love the presentation and setting, and it's made me more interested in your other games. Good stuff!
