First of all: this is absolutely the game of this genre I enjoyed the most this entire jam. The movement felt really good, the powerups (especially the bullet number) felt tangible, and little touches like the camera sweep to check out what powerup/board change the DM was going to do kept a feeling of 'progression/levels' going through the game.
A few little details that I feel would push it over the top:
-Your music is SO SO GOOD, really reminds me of wii sports, and would only be accentuated by making sure everything has jut as good SFX feedback. It would really add the extra 'oomph' onto each different ability.
-Aesthetic is cute, but I'd really like just a little bit more visual difference between enemies. Working with different silhouettes is difficult when it's a cube game, but it may help add to the feeling of progression.
All in all, it brought back great memories of the n64 days. I loved it!!
