Amazing Game!!!
The only feedback I have would be on the difficulty and the “randomness” feeling a player can have in relation to the archers. But for a 1 level game, you check all the marks: fun, short, cool effects, clever game mechanic, nice introduction to the main idea (a tiny sad that breaking blocks isn’t a very used mechanic in the future of the level), a progressive difficulty curve and even a boss! We do feel a nice adrenaline rush by playing your game. Also, I do feel like some part of the UI ended-up beeing unused? Like the 3 inventory slots at the bottom of the screen?
I do recommend to you to either make a few levels and publish the resulting game and have each level be randomly generated (I feel like it would fit very well your game, make a few sections of progressive difficulty and spawn them. That way you can even make a level design adapative to the player’s level! I know how hard that can be, but since your using construct, you’re cheating from the start😛)
GG!
