This is a pretty cool concept! Please update your game page with more information on how to play, it was very confusing at first. I managed to complete Level 1, 2 and 4. I made it to the end at Level 3, but the last door was bugged and had no code to scan.
I think it is a brilliant idea to basically morph your own DNA so that your character gains different abilities. There are some mechanics that must be explained or shown better, for example, you get to move 2 tiles before the enemy moves - this confused me on the timing of the enemy’s movement when trying to avoid being seen. The speed ability also should be explained clearer: i.e. allows you to move 3 tiles before an enemy moves. There is a lack of indication of anything, so perhaps you should at least have an arrow saying “click here” to select your gene for scanning the first door. Explain to the player that the shapes must fit in the scan. When you tell the player to “touch clones”, it is not immediately apparent that the patrolling guards are the clones, so you should either give a backstory or just point out that you need to move into them to get the extra DNA letters needed to unlock the final door.
Although the game lacks polish, I think the base concept is quite unique and engaging to play. I would love to see this idea be developed further!
