You have made a nice game. I want you to know my first impressions, so here they are:
-- PROS --
- The idea was somewhat creative, to be honest;
- The art was great for everything!
- The sound effect for jumping was very satisfying!
-- CONS --
- There was no menu, no pause screen, no GUI;
- There was no indicator to show where the sword would fall from, so it would hit me middle-jump;
- There were no sound effects for swords falling, nor for the death;
-- RECOMMENDATIONS --
- I suggest keeping score, or adding some achievements so the player can have goals;
- I also suggest adding some music in the background;
- I also think there should be a difficulty curve, where the game is easy in the beginning and gets harder over time;
Other than these, I liked the Ukraine flag! Respect to you for that!
