Version used: Demo - v0.1.5.1
I like this game, it's a super well made spiritual successor to Super Hexagon, but it's a bit too hard. Emphasis on too. Here's some of my nitpicks.
1. There's a large gap between casual and hard. Casual is very slow, while hard is OH GAWDD for a good-ish hexagon player (such as myself). It's like putting a slowed down version of Pointless next to Second Dimension.
2. Setting preferred inversion controls bugs out when restarting. Say i set "inside" to inversed. I go to level 2, i die on the inside perspective, and get put on 2D normal mode when i restart. Bam, my 2D controls are reversed.
3. The level restarts go way too quickly. When you first start, you're given a short tutorial or warmup period which lets you get ready. But when you restart, it's riiiight back into the action with a wall directly going for your pointer. Can't even say "let's try again" without needing to move out of the way.
4. Restarting a level is confusing. Every time you restart a level, you go to a random shape and a random perspective. Highly confusing when combined with point 3 as you frantically dodge the triangle spir- dead. I'd want the level to start at hexagon and wait a short bit for me to get ready before throwing literally everything at me.
This is a really great game, despite the nitpicks that i had, and i keep trying and trying over and over. It's addicting!
