Hello!
Good level design, obstacles are clear, nice platforming, simple clean mechanics with unconventional uses, things are well implemented, I liked it! Those guns upgrades made me feel powerful, well done.
A recommendation to improve: you show all controls in the game page, and it spoiled me about the upgrades before starting. You can remove that from the page, since you explain the buttons once I get the mechanics in game.
I very much love the fact that Dynamite gives extra jump height. That is a mechanic you don't tell in your game (sort of a "hidden mechanic" on top of what Dynamite usually does) and you could have use it nicely to design a sequence break. Or maybe you did and I didn't find it!
Would you try to find the sequence break in our game?
Also, is there a map to show while playing? Will you add console controller?
