Interesting concept! I have seen many games which have combine-with-your-enemies mechanic but this one is the best execution of that mechanic!
I wouls suggest adding sound/music, and making it a little easier to grab enemies.
There seems to be a bug where if the only enemy remaining is connected to the player, the game enters a soft lock mode, the enemy can't hurt and neither can you, so even though you should have won, you are stuck on that level until you close the game and play from the beginning again
Overall an amazing entry to the jam! Great job!
