I am glad you liked it. The finish line is around 3000. This is intentional so that it's challenging even with lack of other content. Original plan was to have enemies spawned along the way and traps procedurally generated at random. Then after a while you would reach end of the section with room to rest just before boss fight. But that's just the plan. Most of this is actually already coded I just didn't have enough time to implement it properly.
I was considering adding platforms and it's still an option but I have decided to aim for continuous progression after each run and upgrades. I haven't even touched that yet. Ideas are nice but it all comes to time in the end.
