I liked the idea quite a lot, combining few different well known mechanics and having this! I liked the game, hoped it wasn't beaten so easily, maybe a bit harder. I completely understand only the one level/etc, when doing something like this alone, just crank the difficulty up a lot and test it with some mates or people on discord to get a good balance!
It was fun to play and I'd see myself playing this if it would be longer, now I just beat the game in like 1min or so :D Hope you continue developing this and let me know when you're getting new versions out!
I could see this being a proper game, maybe a bit more mobile suitable but still could have potential!
Hope you get time to review us as well, I know you played the game already! :D
