This was a very interesting spellcasting system! Definitely tests your skills at memorization and drawing the shapes you learn under pressure (probably one of the best spellcasting systems I've found in a game). Probably this spellcasting system would have been great for some kind of PvP game (considering how nicely it incorporates reflexes, memorization and precision. Perhaps having some summoning spells as well to make AoE effects more useful in that pvp context. I wonder if it might be possible to incorporate ratio geometries and similar traits to allow "inventing" new spells by mixing up old ones - sorry for the enthusiastic runt about the idea).
What I didn't like was the level design and how most of the time I ended up just shooting the block I was standing on instead of the enemies. Perhaps being able to hit enemies from the first floor would have been nice? And if the teleport could work on demand and without needing to go to the portals.
Surprised this game didn't have any ratings yet. I think more people should play it.
