This is a really good and simple game! However, my main issue lies in the sad lack of the finished echo mechanics. The concept of the echo mechanic is really cool, but it's unfortunate that it wasn't fully implemented. Without its completion, I find it difficult to rate the game more positively. Nonetheless, the gameplay is simple yet fun, and it provides an enjoyable experience.

One area where the game could have improved is in the inclusion of music or sounds. Adding audio elements would have enhanced the overall enjoyment and experience.

Overall, this is a decent game, especially considering it's your first project. It shows promise, and I encourage you to keep going with your development. It would be great to see how the game evolves and incorporates the intriguing echo mechanics in the future. Good job!

This is pretty fine for a first game :) one piece of game jam-specific advice I'd recommend is to try and incorporate a scoring system into a game like this! It doesn't have to be anything complicated, just adding 1 to an integer whenever you defeat an enemy, and displaying that to the player. Heck, you could have even just made it output in the console.

I also think it's important to scale the difficulty as time goes on. I'm not sure if the current version of the game had it, since I only played for about two minutes, but it felt like the enemy counts weren't increasing and they weren't moving faster. Again, it doesn't have to be anything complicated; making them spawn slightly more often as time goes on, or making them spawn with a slightly higher speed as time goes on, would really make the game more engaging.

A score system would be needed, also music and sounds. Some enemies spawn outisde and get stuck, also you can make them stuck on walls when they are following you, sometimes their animation glitches, and if you don't kill any i think there's no limit of how many they can be at the same time so i think the game could be affected with lag or even crash.

The idea of having echoes of your past attempt is interesting, it's a shame it hasn't been implemented.
