(I suck at platformers 😅)
Key features

• Easy boss fights,
  
• Lots of magnets based rooms,
  
• Up, up, up!

It's not bad, really
I had my rough moments with Teslagrad. It challenges you to beat hard obstacles where precision is the key.
Well timed dodges take you through lasers, well timed magnetic pole activation pushes you away from enemies, lave floor, etc-etc. It looks awesome when you shift between red/blue aura and continue flying through energy spikes.

My issue was that multiple times the character still takes damage and instantly dies even though the dodge was pressed at the same time. True rage was in a charged cubes tunnel, where those lethal blocks slide left-right, there, you WILL spent some time memorising precise path and timing. As well as in many other rooms where exact magnetic repel saves your life. Oh well, at least you respawn quick and in the same room.

It's pretty simple overall, just keep going to upper levels and beat unexpectedly easy bosses (only three).

Played the original 7 years ago.
It still holds up

Good Game and pretty easy to 100%, i recommend this if you like puzzle platformer games or if you're looking for easy steam achievements.
