The game is great. The art is nice, the music fits, the mechanic is interesting. Still, I feel like this game has 2 major design problems:
1. There are 10 levels and only 1 mechanic. While yes that is totally understandable for a jam, I feel like so much potential is lost because the only thing added in the 10 levels are more cursors. You could add blocks that can only be moved by the player, not the cursor. You could add surface areas that make a block slide etc. Typical things you find in a game, but these give it more depth.
2. I personally feel like this doesn't fit with the theme. Yes, I understand the 'idea' behind how it fits the theme, but it just doesn't present itself in game like it. I rather feel like the little target is an extension of the character rather than a cursor.
Still, the game was very fun, played all the levels. Congrats to you for also making it look and sound nice.
Note: I'm not at all saying my game is better, this is just constructive criticism.
