Solid entry for a two dev team. I had fun during my time with the game. Some sound mixing would help, even if you varied and randomized the pitch for each shot and diealed back all sfx and included a single audio track it would help with polish quite a bit.
The gameplay was easy to grasp and this was a fun pick up and play entry. A checkpoint for that boss room would be much appreciated! I wanted to jump right back into my fight with the boss, not work through all the rooms again. For a jam game, lean toward forgiving!
Overall, fun little game with varied enemies and attacks and just the right length. Great work.
