You're very welcome! That's what these jams are about: playing & feedbacking each other's games.
Thanks for posting the link to the updated version! Maybe I should do it too (been fixing and adding the remaining levels since then).
Numbers matter, and exceeding those performance limits never results in 90fps, trust me. Keep batches under 2k, tris down to 1mill (if webgl or laptop). Also, I recently started adding (in the pause menu) of my games, quality settings buttons (low, med, high) - which are set by you inside Unity's Project Settings window/tab. Usually, when the game lags, player's naturally tend to look in the menu for options to reduce quality for better performance. A simple low (25%) mid (50%) high (100%) quality options plays well on many types of devices.
