Played 2 more runs.
Full thunder dosen't work but I think it's fine (you could add a homing thunder skill that makes thunder spawn on enemies)
Full Ice is even stronger than fire, and when you start killing slimes you snowball a ton.
In the end there is balance problem once you descover ice is the strongest. I dunno what your philosophy is about this, but a potential solution would be enemies with elem res so you can't just spam your strongest magic for 10min
other things I noticed:
- when you lvlup you fire(a fireball), so or you add a little cooldown when you pause to atks, or make lvlup buttons on release, not on push
- if you rightlick while in lvlup screen witch will do atk animation(it's very cute but still a bug)
- make pillars transparent when you go behind them. More on that, you should probably do this too for enemies/E.bullets.
- maybe make a list of all your Pows in the pause menu, or on the sides of the screen
