Thank you- we're really glad you enjoyed it! Cool to hear you were considering a similar idea too. We really love what you have gone with.
Great feedback about that level as well. We're considering doing a post-jam update to do some fine tuning and add some more simple levels to introduce each mechanic, so we'll definitely revisit that one while looking at the overall progression / balance. Coincidentally, I actually hid a secret switch to turn off the heating elements in that very level (mostly for my own satisfaction haha), but it's definitely not easy to find unless you're actively looking for it...
Thanks again for playing and for the encouragement - we'll definitely be doing another jam in future!
