I find it respectable that you managed to have such good pacing in the game. You started small, introduced more elements and even had a boss fight at the end. Very good job! I found the latching mechanic to be very original and enjoyable with a lot of potential for more interaction, like connecting objects. The boss had some dead angles where, upon latching, it could not reach me with its attacks anymore, so maybe check all directions and see if the boss attack range fits? (I just guess that is how you intended it). Good job again!
